Hey, all -
I'm attempting to write a script to put in cron.weekly that will find
the 25 users who use the most disk space and email them a warning.
My relatively simple question is:
Is there anything in bash that is the equivelent to the old basic
mid/left/right way of cutting down a variable?

How about something like:

to get the names... and then wrap it up in a mail command... it's not a
bash script since it forks a few times, but it's a quick'n'dirty.

That is also correct. I had forgotten.
But, my original point is that it is probably better to specify the full
pathname of a command.
X=$(/bin/ls) will generally result in identical results as:
PATH=/bin:$(PATH)
X=$(ls)
But, specifying the full pathname also forces the command to be executed
Yes, but several Unix systems supply an old style Bourne SH as well as a
POSIX shell (essentially ksh scaled down) and ksh. KSH implemented the [[

For the most part, the syntax will work in most Bourne derived shells.

Yuck, yuck, yuck! It looks like everyone was pointing out ways to
use sed to accomplish this. Now, sed may give you extra
power, but when
writing shell scripts, I prefer to avoid using external commands where
possible. To that extent, consider:

In general, I try to write my scripts portable so that I can use them on
other platforms. In the past 5 years, I have had jobs with Tru64 Unix, HP-

SuSE). Most of my personal scripts are small and work across platform. My

Not strictly true; you can still find them. However, ISA has become a
