Hello.
POST YOUR COOLEST SCRIPTS! <3 (trick or treat)
I thought I'd create this thread for all you script enthusiasts out there.
I've newly started basic shell programming, and just the very thought of it
gives me this warm fuzzy feeling of having scripts assisting me in shaping
things exactly the way I want them. I know you all gurus out there might be
shaking your heads in despair to this, but I'm just trying to increase my
passion and that of others further, if such a thing is at all possible.
For whatever purpose you made your scripts, as long as you're proud of them
and they're not classified as top secret, please be a sport on this
glorious night of halloween and share them with us!
Anyway, here are my humble contributions:
crlf.sh:

#
# Removes CRLF line termination in ASCII files.

for file in `find . -type f ! -name ".*"`; do
if [ "`file -b "$file" | grep "text.*CRLF"`" !=3D "" ]; then
perl -i -pe 's,\r\n,\n,g' "$file"
echo "$file: Done"
fi
done
mode.sh:
#!/bin/sh
#
# Sets default ownership and permissions.

tree.sh:
#!/bin/sh
#
# TREE.SH 1.0
#
# Reads a directory or file list,

#
# -a, --all Prints all files, not just directories.
# -h, --help Prints usage information.
# -l, --list Reads a list of files from stdin.
# -v, --version Print the version and exit.
