Question About Path And Commands

Question About Path And Commands

[Rejean Proulx]

I want to set up a weekly cron with the diff and the mail command.  Cron requires that everything is fully qualified.

How do I tell where the diff and mail commands are found?  For example, I know that cp is in ;/bin/  My script keeps failing and I am trying to fix it.

The command is 'which' so, for example, to find where cp is you would do:

which cp

You have two choices. The first and easiest is to set the path in
your
script so that you don't have to type in fully qualified commands the
hole
time. You can do that by placing this line near the top of the script
(note,
this is a commonly used path, and you may need to add and/or remove
directories from it):

path=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin

The other way is to use the whereis command to find every program you
need,
and then fully qualify everything. For example:

whereis cp

Would tell you where cp is. Here is the output from that command on
my
system:

cp: /bin/cp /usr/bin/cp /usr/man/man1/cp.1.gz
/usr/share/man/man1/cp.1.gz

I don't recommend this aproach for two reasons. First, it can be very
time consuming if you are using a lot of programs. Second, if you
want to give someone else your script for some reason, it may or may
not run depending on if programs are in a different location.
