Hello!
This script produces a real sweet file and directory tree.
I am trying to simplify this -- it is too big for its own good.
I must remove all the bullshit but the -a switch.
And I'm sure the same thing could be accomplished in just a few lines.
Here is what it does:
# fs-tree
#
/usr/home/vaaf/mp3/out
+-----benny_benassi-whos_your_daddy-promo-cdm-2005-nbd
+-----bugz_in_the_attic-booty_la_la-mystery_and_matt_early_remix-vinyl-2005-mtc
+-----chris_cox-live_from_park_pavilion_atlanta-sat-01-01-2006-hsalive
# fs-tree -a
#
/usr/home/vaaf/mp3/out
+-----benny_benassi-whos_your_daddy-promo-cdm-2005-nbd
| +-----00-benny_benassi-whos_your_daddy-promo-cdm-2005-nbd.m3u
| +-----00-benny_benassi-whos_your_daddy-promo-cdm-2005-nbd.nfo
| +-----00-benny_benassi-whos_your_daddy-promo-cdm-2005-nbd.sfv
And so forth.
Here is the original script:
#!/bin/sh
#
# Read a directory or file list,then write a tree.
# $URBAN: fs-tree.sh,v 1.0 2005/10/24 15:05:09 vaaf Exp $
#
# -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.
#

#
die () {
echo "$tag: Error: $*" 1>&2
exit 1
}
# *** Usage
#
# Prints an optional string plus part of the comment header
# (if any) to stderr, and exits with code 1.
#
usage () {
lines=`egrep -n '^# (NAME|AUTHOR)' $0 | sed -e 's/:.*//'`

And here is my attempt to simplify it.
Now, mind you that this doesn't even work!
#!/bin/sh
#
# Read a directory or file list, then write a tree.
# $URBAN: fs-tree.sh,v 1.0 2005/10/24 15:05:09 vaaf Exp $
#
# Print files in addition to directories: -a
#
tree() {
do=`tr '/' '\001' | sort -f | tr '\001' '/' |
sed -e 's,^.$,,' \
-e '/^$/d' \
-e 's,[^/]*/\([^/]*\)$,+-----\1,' \
-e 's,[^/]*/,| ,g'`
}
all="-type d"
while [ $# -gt 0 ]; do
case $1 in
-a) all="" ;;
esac
shift
done
find . $dir $all | tree
--
I'm the biggest rookie you've ever seen.
But I'm thinking this still looks too advanced for its purpose.
Any suggestions?
Thanks!
