I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.

Hi,
I am using su within a for loop. As you might expect, it prompts for password during each loop execution. Here is my piece of code:

Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)

dh_compress
DH_COMPRESS(1) Debhelper DH_COMPRESS(1)NAME
dh_compress - compress files and fix symlinks in package build directories
SYNOPSIS
dh_compress [debhelperoptions] [-Xitem] [-A] [file...]
DESCRIPTION
dh_compress is a debhelper program that is responsible for compressing the files in package build directories, and makes sure that any
symlinks that pointed to the files before they were compressed are updated to point to the new files.
By default, dh_compress compresses files that Debian policy mandates should be compressed, namely all files in usr/share/info,
usr/share/man, files in usr/share/doc that are larger than 4k in size, (except the copyright file, .html and other web files, image files,
and files that appear to be already compressed based on their extensions), and all changelog files. Plus PCF fonts underneath
usr/share/fonts/X11/
FILES
debian/package.compress
These files are deprecated.
If this file exists, the default files are not compressed. Instead, the file is ran as a shell script, and all filenames that the shell
script outputs will be compressed. The shell script will be run from inside the package build directory. Note though that using -X is a
much better idea in general; you should only use a debian/package.compress file if you really need to.
OPTIONS -Xitem, --exclude=item
Exclude files that contain item anywhere in their filename from being compressed. For example, -X.tiff will exclude TIFF files from
compression. You may use this option multiple times to build up a list of things to exclude.
-A, --all
Compress all files specified by command line parameters in ALL packages acted on.
file ...
Add these files to the list of files to compress.
CONFORMS TO
Debian policy, version 3.0
SEE ALSO debhelper(7)
This program is a part of debhelper.
