SPACES TO UNDERSORE 1 LINER

Do you hate users who put spaces in file names, preventing
you from doing any sort of scripting?

Well then this is the little one-liner for you to pop in a
shell script then...

for i in $1 ; do mv "$i" `echo $i | sed 's/ /_/g'` ; done

the echo $i | sed 's/ /_/g' is surrounded by back-tics not
regular quotes.

NEW TIP BETTER THAN OLD TIP!

Sorry about the Y2K tip, we have been
testing a new Tip mailer. Hated it!
Here is the real tip that was
suppose to go out today:

------------------------------

WALK THE CUBES

Some times at work there are
dry periods when the users don't
call. Walk the halls even if
there is nothing to do. Being
seen by users makes them feel that
you are always around for them.

Some users are hesitant to call at
times, and some feel you are never
around to help. When you walk
the area ask different users each
time if everything is alright.
A simple way to stay proactive.

Also, if you charge your time
back to a department, make sure that
you walk past managers offices. They
will feel that you are there to work
on the employees problems and
they're being well taken care of.
Even if everythig is okay, and they
ask what the problems are, let them
know you are there because you care.

Alittle TLC goes along ways.

CHANGING PERMS RECURSIVELY

*** NOTE: Odly enough, the previous mailing
of this tip did not go through do to a
permissions problem. Sorry.

To change permissions recursively for all files in a
directory

find dirname -exec chmod xxx {} \; -print

where dirname is the directory you want to change permissions.

Unix Tip: METAVALUES FROM A SHELL SCRIPT

Unix Tip 3295 - February 16, 2015

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

METAVALUES FROM A SHELL SCRIPT

Getting a file's size, link count or other metavalue in a shell script:

When you want to extract a specific piece of meta information about a
specific file (such as it's size, link count, or one of its time stamps)
you can use the find -printf option and any of the various
%-directives listed in the find(1) man page. Example:

size=$(find some_file -printf "%s" )

(under ksh, bash, and similar shells). Here the $() form
is used as a more readable equivalent to the older `` (back
tick) operator. (Another advantage to the $() is that it
is nestable). To get the user name of the owner of a
file "foo" you could use:

set owner = `find foo -maxdepth 0 -printf "%u"`

(here we're using the csh syntax). This also uses
the -maxdepth option in case "foo" is actually a
directory name; since we don't want find to
spend time traversing directory and printing the
owners to ALL of the entries thereunder. A
maxdepth of zero ensures that this will only print
the detail we want on the specific link that we
named on the command line.

This can be much more flexible than the options provided
by the test command (try to see which of two files is
larger, or if to files are owned by the same user or
assigned to the same group, using just test).

CHANGING OWNERS REGULARLY


If you're an SA and need to change file ownership permissions
on a regular basis, this script may help you. If you want to
change the ownership of all the files owned by abc user to xyz
user, this can be accomplished by chgowner abc xyz with this
script. Of course you should have rootly powers(deity) to change
other people's files ;).

----Cut Here ----

#!/bin/ksh
#chgowner - written by Rainer Raab on Solaris 2.5.1

if [ $# -eq 2 ]; then
OLDOWNER=$1
NEWOWNER=$2
else
echo "usage: `basename $0` [original file owner] [new file owner]"
exit 1
fi

PATH=/usr/bin:/usr/ucb:/usr/local/bin

FILES=`ls -Al|grep $OLDOWNER|awk '{print $9}'|grep -v "./"`
for i in $FILES; do
chown $NEWOWNER $i
done

Unix Tip: CLEANING DIRECTORIES

Unix Tip 3293 - February 14, 2015

CLEANING DIRECTORIES

The creation of many temporary files
in Unix during compilations, occupies
a lot of memory space. This can be
got rid of by using a simple script.

find $1 \( -name a.out -o -name '*.o' -o -name 'core' -o -name '*.ii' -o -name '*.ti' -o -name '*.class' -o -name '*.pur' \) -exec rm {} \;

Save the above line in a file and run
this file after changing permissions.
For example, if the file containing
the above code has the name 'clean',
then:

example% clean

will remove all the files specified
in the script in the directory and
all other subdirectories within it.
You can add or remove any number of
files in the script, to suit your
needs.
