Crappy title, yes. But I honestly have no idea what this particular line of code does, aside from the fact that it probably passes some argument into a perl script. Here's the line:
dbget.pl "params::INSTANCES_*" | /bin/sed -e 's/^setenv \(.*\) '"'"'\(.*\)'"'"'; /\1 = \2/ ' > .gen_inst_cache.$$
I'm guessing there's a bunch of Regexp going on in here? That's probably why it looks so unreadable in the first place.
Thank you for any help.
The script called dbget.pl called with "params::INSTANCES_*" as parameter will generate some output on standard output. This stream will be directed in stdin to sed, that is a stream editor.
Sed will substitute any line beginning with:
setenv (something) '(somethingelse)';[space]
into:
(something) = (somethingelse)[space]
The substituted output will be directed to a file called .gen_inst_cache.$$, where $$ is the pid number of your calling shell process.
