Unix Tip: FINDING A STRING

FINDING A STRING

How to find a string somewhere on the system. Many times we are called to search for a string, but we have no idea where it may be lurking. Judicious use of the find and grep commands will make you a hero with your co-workers.

# find . -type f -exec grep "string or options" /dev/null {} \;

Normally using only:
# find . -type f -exec grep "string/options" {} \;

Produces the target string, but you will have no clue as to where it is located, making this almost as frustrating as using windoze! Remember when grep'ing against multiple files the filename will be listed before the match.

$ grep there *
foo:I found the target here
bar:You are there

In our find command we use /dev/null as a file to search against, since we know the search will always fail if the string is found in "{}" there filename is printed. To borrow from a famous quote: "Pretty tricky sis!"

RANDOM LINES FROM A FILE

A easy way to retrieve random lines from a text file:

perl -e '$count = 10; @line = <>; for (1..$count) { print $line[int rand @line] }'

example:
% cat /etc/passwd | perl -e '$count = 10; @line = <>; for (1..$count) { print $line[int rand @line] }'

Unix Tip: EXTRACT THAT LAST FIELD

UNIX HOT TIP

Unix Tip 3188 - October 29, 2009

http://www.ugu.com/sui/ugu/show?tip.today

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=


EXTRACT THAT LAST FIELD

You can use 'cut' to extract the last field of a line if you know how many fields there are, eg:

field=`cut -d: -f8 file`

But if you don't know the maximum number of fields or the number of fields per line are not consistent, awk can come to the rescue. awk has the inbuilt variable NF for the number of fields. By using this variable we can use it to extract the last field by using:

field=`awk -F: '{print $NF}'`

or you can use calculations to retrieve any field relative to the last field. For example to retrieve the second last field, use:

field=`awk -F: '{print $(NF-1)}'`

For some reason many admins forget the field order of the crontab file and alway reference the man pages over-and-over. Make your life easy. Just put the field definitions in your crontab file and comment (#) the lines out so the crontab file ignores it.

#minute (0-59),
#| hour (0-23),
#| | day of the month (1-31),
#| | | month of the year (1-12),

POWER OF BACKQUOTES

Backquotes are the most powerful things in Unix. More than one Unix commands can be run simultaneously on the prompt. In csh,

% find . -name "*.txt" -print

gives the path & names of the files with extension ".txt" in current directory and its subdirectories. If you want to open these files in vi together then

% vi `find . -name "*.txt" -print`

Similarly,

% find . -name "*.txt" -print
<listing of all txt files. in current directory/sub-dirs>
% vi `!!`

this will open all those files in vi listed by find command.

PING THE HOST TABLE

Here is a quick way to ping all the hosts in your host table. NOTE: Just make sure that there are no blank lines in it, and verify the ping command on your system exist after one ping. Your mileage may differ slightly.

$ grep -v "#" /etc/hosts | awk '{print $1}' | while read host
> do
> ping -c 1 $host
> done

Or script it:

#!/bin/sh
grep -v "#" /etc/hosts | awk '{print $1}' | while read host
do
ping -c 1 $host
done

Unix Tip 3183 - October 24, 2009

http://www.ugu.com/sui/ugu/show?tip.today

A SHAMELESS PLUG

The Best Tip I can give you right now is to pick up a copy of UNIX HINTS AND HACKS By the Creator of UGU.

It is available at Barnes & Nobles, Borders, and Technical book stores.

Some of the past tips from UGU can also be seen in the book.

http://www.amazon.com/exec/obidos/ASIN/0789719274/unixguruuniverse

Here are what some UGU'ers are saying about the book:
-----------------------------------------------------
mikec@sficorp.com from Green Bay, WI , August 21, 1999
FANTASTIC - FIVE STARS *****
This is a great book for those looking for quick solutions to common real work scenarios. If you are responsible for Unix (yes including Linux) systems this is one book you have to have. For coding solutions the book usually shows both shell script and perl examples for the same problem

jbaduria@hotmail.com from San Mateo, CA, USA , August 19, 1999
GREAT BOOK!! - FIVE STARS *****
Finally a book that deals with the real things that most UNIX system administrators face. It saves you the trouble of finding out things only after you face it. You could save yourself a lot of time solving problems that could have been avoided by reading this book. With the price nothing beats it. Not even those $30+ books.

link2000@n-link.com from Tx, Usa , June 25, 1999
GREAT BOOK - FIVE STARS *****
This is a great book. It has many tricks that are geared toward real world experience that are not covered in any other book I have seen. I especially liked the section geared toward getting your first job as an system admin. It is one book worth buying. For all kinds of information for less than 15 dollars how could you go wrong.

REPETITIVE TASKS WITH XARGS

Save yourself a lot of typing when you have to perform repetitive commands on a list of files. Put the list of files in a text file with one file per line ie: find . -name version.C > filename Then have xargs build a command line for each file in the list as follows:

cat filename |xargs -n 1 cp anotherfile

This will copy anotherfile over all the files listed in filename one at a time until the end of filename is reached.

Suppose we want to check whether the web server is running or not, but we don't have any browsers ( lynx, IE, Netscape ...), then there is a simple way of doing that. Just telnet to that machine on the http port ( port no 80 in general).

% telnet <ip addr> <port no>

And then, say "get /" (without quotes). If the webserver is running, it displays the HTML script of the homepage or basic info and closes the connection to the remote host.

% telnet yahoo.com 80
Trying 204.71.200.245...
Connected to yahoo.com.
Escape character is '^]'.
get /
HTTP/1.0 302 RD
Location: http://www.yahoo.com/

Connection closed by foreign host.

Unix Tip: CTRL-D ANOTHER USE

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

UNIX GURU UNIVERSE
UNIX HOT TIP

Unix Tip 3180 - October 21, 2009

http://www.ugu.com/sui/ugu/show?tip.today

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=


CTRL-D ANOTHER USE

Many Unix Admins use the C shell as their interactive shell. An often used feature of Csh is file completion - initiated with 'set filec'. It allows the Csh user to type in partial file names, and then press escape to get them completed where possible. A little known side effect of this is that Control-D (^D) will now generate file listings in the middle of command lines.

Example 1: (where @ is a space)
host > @^D
Lists the current directory

Example 2:
host >ln -s /usr/^D
Lists the /usr directory

host >tar cvf /dev/nrtape /usr/m^D
Lists all m* files in the /usr directory

In each case, after the listing, you get a new command line and are placed at the last point of edit.

Very handy if you you know what you wanted to do but forgot what you wanted to do it with!

HIDE THOSE FILES

If you want to have some hidden directories on your server (warez etc.) then make a directory with permission 111.


% chmod 111 foo/

All the contents will become hidden:

% cd foo
% ls -al
Cannot access directory .: Permission denied

The directory will have to opened back up (755) in order to see or access the files or the directory. To remove the directory and its contents, it will also need to have the permissions opened.

Unix Tip: PERFORMANCE OF CROND TASKS

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

UNIX GURU UNIVERSE
UNIX HOT TIP

Unix Tip 3177 - October 18, 2009

http://www.ugu.com/sui/ugu/show?tip.today

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=


PERFORMANCE OF CROND TASKS

A good tip for getting better performance in crond tasks is choosing a better time for launching them.

If the process that we want to launch needs few time, but can overload the system easily, you can launch the task in hours that the work is busy and -and HERE is the tip- in strange minutes. That's why lots of people launch their crons at midnight, but nobody uses to do it at 00:13, in example.

That tip can obtain his best in hourly-launched tasks. If that kind of tasks are launched all at the same time, the system will overload without any use. You can delay that kind of tasks (one at 13th minute, other at 17th minute,other at 27th minute...) and obtain better performance without work. That will avoid overloading caused by launching several tasks at the same time.

The best is that administration tasks do not overlap, but this is not always possible. If you can do it, it's better you do it.

Using nice is also a good idea.

But the best is making a log of the uptime during a week. You can be surprise, because all the staff of a department of a firm use to do the coffee-break at the same time; it's the perfect time for making some administrative tasks. :-)

But do not clear the forbidden extensions -the famous find /home -name core -exec \{\} \; and other stuff like tmps, ~s and so on- of the system at work time, or you will have a queue of staff people very, very angry knocking at your door.

I SEE YOU WITH FUSER

In System V, you can use the following command to see who is accessing a particular file system:

fuser <file system>

For example, to see who is accessing the /cdrom directory:

fuser /cdrom

This command is useful if you wish to unmount a file system but the system is unable to do so because it is being used.

http://www.ugu.com/sui/ugu/show?tip.today

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=


KILLING ALL USER PROCESSES

The common method for killing all of a users processes usually involves grepping the users name from 'ps', then using awk to get the process id's and submitting them to 'kill -9'.

Sys V
ex: kill -9 $(ps -fuusername | awk '{ print $2 }' )

BSDish
ex: kill -9 $(ps -aux |grep username | awk '{ print $2 }' )

The problems with doing this way are that it is slow, and more importantly, it doesn't always kill all of the processes on the first try.

There is a way to do this that always kills all of the users processes the first time, and is very fast:

su - username -c 'kill -9 -1'

NFS HANG FIX ON HP-UX

In an NFS environment (Hp-UX based), sometimes no user is able to log-in when home directories are mounted using automounter). As user validation occurs, the user .profile is executed but no shell prompt appears unless the user presses CTRL-C.

The Solution to this is to kill the portmap & inetd and restart the two daemons. The problem will then be sorted out.

Public Relations

One of the best things an admin can do is to have good public relations with the user community.

Don't just be there when problems arise. Go out to the user community when things are working. High visibility is the key.

If the users see you around and there are no problems they will believe that you care to take the time for them.

Try not to let the users always go come to you.

Go to those users that you never here from The perfect users, the ones that leave you alone. Often the don't have an understanding of what you can do for them.

I know many will say, "I don't have time!" Just a calm walk through a department is really all it takes, sometimes you never have to stop.

Unix Tip: AWK QUICK COLUMNS

Unix Tip 3167 - October 8, 2009

AWK QUICK COLUMNS

Most of the time when you use awk from the command line, you're doing something simple like this:

ps -ef | grep netscape | awk '{print $2}'

To save typing, use this script when you only want to use awk to print out one or more columns:

------------------- CUT HERE ---------------------------
#!/bin/ksh
# awkc - print out one or more columns

p=\$$( echo $1 | sed 's/,/,\$/g' )
shift
eval "awk '{ print $p }'" $*

# eof
------------------- CUT HERE ---------------------------

Now you can do things like:
ps -ef | awkc 2,1
or
awkc 1,2,3 /var/adm/messages*

Unix Tip: -------- REMOVE THE DASHES

Unix Tip 3162 - October 3, 2009

http://www.ugu.com/sui/ugu/show?tip.today

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=


-------- REMOVE THE DASHES

Have you ever accidentally created a file beginning with '-'? It happens often by mistake and from the first look it seems like you can't delete the file (rm thinks the initial - is an option, and doesn't recognize the file).

The simple, quick way around this is the -- option to rm. Say you had the file ---hey in the current directory:

$ ls ---hey

/bin/ls: unrecognized option `---hey'
Try `/bin/ls --help' for more information.

$ ls|grep hey
---hey

$ rm ---hey
rm: unrecognized option `---hey'

Try `rm --help' for more information.
$ rm -- ---hey

( ls also has an -- option: )

$ ls -- ---hey
/bin/ls: ---hey: No such file or directory
$

Unix Tip: SEPARATE SHELL COMMAND HISTORY FILES

SEPARATE SHELL COMMAND HISTORY FILES

In any X based desktop when the number of pseudo terminal windows are more then one, the common shell history file (KSH) becomes a nuisance. Here is a way to have separate, safe and limited shell command history files.

Put the following code in your shell RC file.

--------------------------------CODE START------------------------------------
# Form a unique name for the shell history file using the tty output and
# set the shell variable HISTFILE to point to that
# This solves the problem of mutiple shells using the same history file
# and causing the confusion....
histf=`tty | awk 'BEGIN {FS="/"; nm=".shist_"} { for (i=1; i<=NF; i++) nm = nm
$i;} END { print nm;} '`
export HISTFILE=$histf
\rm -f $histf
echo History file is $histf...
--------------------------------CODE END------------------------------------
