Got a monitor you don't want stolen,

FTP AUTOMATED TRANSFERS
Automatic file transfer through a script
between machines using FTP.
If one wants to transfer files between
UNIX machines, here are the steps to follow.
1. The .netrc file
a. create .netrc in the home directory.
b. add this line
machine <target machine> login <login name> password <password>
e.g.
machine abc.mydomain.com login deepak password deep123
c. chmod 600 .netrc
2. The Script:
ftp abc.mydomain.com << endl
prompt
put test1.c
quit
endl
This should do it.

Unix Tip: RESTARTING PROCESSES

UNIX HOT TIP
Unix Tip 3387 - May 18, 2012
http://www.ugu.com/sui/ugu/show?tip.today

RESTARTING PROCESSES
There are times when you are
testing a process and have to
restart it again and again.
Instead of doing a ps -ef to
know the pid and kill it manually
every time, you can automate the
process by using the following in
a script.
kill `ps -ef | grep \`whoami\` | grep myProcess | grep -v grep
| awk '{print $2}'`
The ps command on your flavor may
use "ax" instead of "ef". Where
myProcess is the process that needs
to be restarted. The awk commands
gets the 2nd field of the line, which
in this case is the PID.

FILES TOO LARGE FOR FLOPPY
Ever want to find the files
that won't fit on a floppy
when you need to do a
doswrite to export something?
This will do it:
find . -size +1440k -exec ls -ld {}\;
Note: This will list the files
in the directory where you are,
that exceed the maximum size
in kilobytes for a high-density
DOS format floppy. Please don't
forget the single dot after
"find" and you can change the
1440k to whatever you want.
(I once had a need to find
stuff that was 3 megabytes and
over to keep out of a directory
so I used +3000k in place of the
+1440k above.)

I uses it because some time when

converted to UPPERCASES, which is
undesirable.

VI EXECUTION
While writing shell scripts
in vi, have you ever considered
the time wasted by going in
and out of vi to test your
commands by executing them on
the command line.
To increase your productivity,
it would be a lot quicker if you
could execute these commands
from within the editor and view
their output before writing them
to your script.
This is possible and quite
straight forward. Enter the
following within vi
:!testscript
(i.e. colon exclamation mark)
Then enter your command as you
would at the $ or # prompt.
The command executes, the result
is displayed and you are propmted
to press return to continue.

Unix Tip: A PROPER USE OF FIND
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
UNIX GURU UNIVERSE
UNIX HOT TIP
Unix Tip 3375 - May 6, 2012
http://www.ugu.com/sui/ugu/show?tip.today
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
A PROPER USE OF FIND
Most often we find a file
using the 'find' command,
but sometimes we know that
find does not give results
if not used in a proper way.
Here is an example to
demonstrate it.
Assume that /project/src is a
symlink then
find /project/src -name ...
symlink will not be followed.
One alternative way is to use
the command
cd /project/src; find . -name ...
but /project/src may not exist
or could be a dangling symlink!
So use the following command to
overcome this.
cd /project/src && find . -name ...

Unix Tip: STALE MOUNT HANGS LS
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
UNIX GURU UNIVERSE
UNIX HOT TIP
Unix Tip 3374 - May 5, 2012
http://www.ugu.com/sui/ugu/show?tip.today
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
STALE MOUNT HANGS LS
Often times a stale NFS mount
point can hang a long listing
of a directory (ls -al).
To avoid this make the mount
point down one level.
So instead of:
mount rocket:/people /people
If the system rocket was down
the chances of a long listing
% ls -al /
of the root directory would
hang for a long period until
the NFS mount timed out.
Avoid this with most flavors
by
mount rocket:/people /rocket/people
then a long listing of root
% ls -al /
would work, but
% ls -al /rocket
would hang due to the stale
mount point.

DAILY BACKUP CHECK
System administrators have to

the daily backup is sucessfully
completed.
One way is to
maintain a short log file which
will log 4 or 5 lines everytime
the backup is completed.
The latest backup results will be
automatically checked by System
administrator on login, if he adds
these lines at the end of his
.profile file.
