Re: running shell script in cron

I wonder whether that program really worked outside the cron job. At least the command

cd $sc `script1.pl S & `
[download]

looks weird (or there are some arcane corners in shell scripting I'm still missing). Could you explain what it is supposed to do? I've never seen the use of the ampersand inside backquotes...

I wonder if there is some missing assignment (result of ``, which would still make `cd` fail in a normal, mordern bourne-like shell) or a missing semicolon (after the `cd` argument) ...	[reply] [d/l] [select]

I was thinking that using & inside backquotes wouldn't work (and it doesn't make much sense since the caller would have to wait for the completion anyway). I tried it on Cygwin Perl, and at least it works here (using bash for shelling out). I don't know whether this is supposed to work in general. Another strange thing in your code is that you have cd $sc `...` [download] So provided your backquoted string substitutes to blablabla, you would have something like `cd $sc blablabla` [download] What is this supposed to do? -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]
