at command scheduling and perl

tuxandme · 06-09-2005, 08:57 AM

I am trying to let a perls script run on a certain time
but when i do:
at TIME DATE < script
where script is a perl script
it doesn't do anyting
but when i do:
at TIME DATE < script2.sh
and script2.sh is:
#!/bin/sh
./script

it works

Can someone help me with the question:
why doest at run my normal perl script directly?
tnx...

The at commands reads lines from standard input and executes them using /bin/sh.

By sheer coincidence, your regular script contains lines that are executable by /bin/sh (well, not sheer coincidence, that's why it is called a shell script)

Anyway, at will try to execute your perl script using /bin/sh, which will most likely result in a pile of errors, since /bin/sh usually can't make sense of perl commands.
