my server uses ~ 20 modules. I never experienced any problems within 20 years.I used to install them by CPAN, however experienced recently, that they all are part of the Fedora repository, thus I'l...

a 20 years ago I wrote a very large and complex server in perl. That PERL code wasn't "very crude", but fits to all todays standards,

add a #!/bin/sh at line 1

sed -i 's/\\/\//g' <script> will do the rest.

then you will have something like:

#!/bin/sh
cd "/java/JARS"

that's simply not true. Windows is a feature rich OS delivering much more than a base system in a freebsd sense. There are a shell, a editor, a paint program, and a good-for-most word processor: the...

windows and *nix are two very different OS'ses. *nix has a long history of time sharing of teletypes (70ths) or ascii video terminals (80ths) attached on small or large (super)minicomputers, as well...

numerical comparison.

this is odd as $PWD stores the actual working directory, which might be in some cases the home directory, where .profile resides, but in most not. Correct syntax is
