Advice: Always use the whole path to a command in the cron and the script the cron calls.

When calling a particular command, let's say grep, always give it the whole path to the command.

grep is a good example of this because there are multiple versions of it installed on most systems and each as different commandline switches.

Typically when this is the case the man page for that utility in question will give you the whole path of each version. As an example, here is the first portion of the man page in Solaris for the grep Utility:

Code:

/usr/bin/grep [-bchilnsvw] limited-regular-expression 
     [filename]...

/usr/xpg4/bin/grep [-E | -F] [-c | -l | -q] [-bhinsvx] -e pattern_list... 
     [-f pattern_file]... [file]...

/usr/xpg4/bin/grep [-E | -F] [-c | -l | -q] [-bhinsvx] 
     [-e pattern_list]... -f pattern_file... [file]...

/usr/xpg4/bin/grep [-E | -F] [-c | -l | -q] [-bhinsvx] pattern 
     [file]...

As you can see there are two different versions available, and depending on which one you call, you have different options on how to use it.

Also, please note that only one of these is, by default, in you're path so if you want to use the other, more powerful, version (the one in user/xpg3/bin) you have to call it by the whole path. Especially when scripting with it.

Hope this helps,
