Additional: if $MY_PATH has the potential to contain whitespace it gets a little more tricky. After some mucking around I did find this solution in bash using arrays:
Note: set -f is required to stop glob expansion of wildcards within the F2 array as we want to pass the wildcards onto find

Hello -
I have a bash script which does some logging, and I'd like to include the line number of the echo statement that pipes into $LOGGER:
MYPID=$$
MYNAME=`basename $0`
LOGGER="/usr/bin/logger -t $MYNAME($LINENO) -p daemon.error"
...
echo 'this is an entry into the log file' | $LOGGER

I have a script that takes an option for server pools to run the script against. The option is given as a comma separated list (ie, -p 201,204,301).
I'm using eval and brace expansion to get those pool numbers into an array. It works fine unless only 1 pool number is given. Here's the code:

Hello,
is there a kind soul who can answer me, does the SH support double substitution known as indirect expansion similar to BASH? The syntax for bash is ${!var}.
For instance in bash I can write something like this:
VAR="value"
REF_VAR="VAR"
echo ${!REF_VAR}
and get the "value"... (1 Reply)

dbs-edit-patch
DBS-EDIT-PATCH(1) Debian Build System DBS-EDIT-PATCH(1)NAME
dbs-edit-patch - Edit a DBS patch
SYNOPSIS
dbs-edit-patch [options] patch
dbs-edit-patch -h|--help
DESCRIPTION
dbs-edit-patch is script to generate or modify patches for Debian source-packages in DBS format.
WARNING
dbs is deprecated, please switch to the `3.0 (quilt)' Debian source package format instead. See http://wiki.debian.org/Projects/Deb-
Src3.0#FAQ for a short guide how to do it.
OPTIONS -h, --help
Show summary of options.
-t dir, --tmpdir=dir
Directory for the temporary files, default is /tmp or if set $TMP.
-s dir, --sourcedir=dir
Top level directory of the debian-package source-tree, default is the present working directory.
-P dir, --sourcepatchdir=dir
Directory containing upstream patches.
-T dir, --sourcetardir=dir
Directory containing the upstream tarball.
-p level, --strip=level
Striplevel -p of patch (Option -p of diff(1)), accepted values are 0 and 1, default is 0.
ENVIRONMENT VARIABLES
TMP Sets the directory for the temporary files, can be overridden with -t dir.
debian/vars
dbs-edit-patch will automatically use variables defined in the optional debian/vars file.
When a file debian/vars.in exists and debian/vars either does not exist or is older than any of the following files: debian/vars.in,
debian/changelog, debian/rules or debian/control, then dbs-edit-patch will try updating the vars file by running the following command
make -f debian/rules -W debian/vars.in debian/vars
EXAMPLES
Edit the 021_debian patch of Heimdal:
~/heimdal-0.3d> dbs-edit-patch -t/tmp 021_debian
Extracting source heimdal-0.3d.tar.gz ... successful.
Applying patch 001_replay ... successful.
etc.
Copying heimdal-0.3d to heimdal-0.3d-old ... successful.
Applying patch 021_debian ... successful.
Edit files under /tmp/021_debian/heimdal-0.3d as required, then put a short description into /tmp/021_debian/patch-description if desired,
and finally execute /tmp/021_debian/dbs-update-patch to save the results.
Technical note: dbs-edit-patch extracts all patches before 021_debian into /tmp/021_debian/heimdal-0.3d, copies the result to
/tmp/021_debian/heimdal-0.3d-old, and applies the last patch 021_debian (if it exists). Also, it creates a shell script which will create
the diff between the old and new directories:
~/heimdal-0.3d> ls -la /tmp/021_debian
total 12
-rwxr-xr-x 1 bam users 112 Jan 31 13:31 dbs-update-patch*

find -name "*.bak" -print0 | xargs -0 --no-run-if-empty rm
find -name "*~" -print0 | xargs -0 --no-run-if-empty rm

test ! -e patch-description || cp patch-description new_patch
