Hello guys.
In my script, i have the following code:
I need to check if the user gave a path to the script, or if he just pressed enter?
I know what to do between the 'THEN' and 'ELSE' statements.
I just need to know how to check if $path is really set or not.
I want to check to see if a variable is set - and if not set it to something
ie. variable name test
I want to check if $test is set
then if there is nothing set against this currently - then set it to 0
Whats the best / shortest way of doing this in a script? (3 Replies)
I need to check if $1 or $2 are empty before continuing but I don't know if bash has any logic of the sort. This is what I'm looking for - except that "and" doesn't seem to work.

Hello everyone, I'm trying the best way to implement a check on a variable ... in particular I need to assess the content of characters and numbers , I tried on various manuals bash scripting but I could not figure out how to do ... any help? (3 Replies)
Apologies for the utter triviality of this question, but we all have to start somewhere! I've also tried searching but this question is pretty vague so I didn't (a) really know what to search for or (b) get many relevant hits to what I did search for.
Anyway, I'm in the process of self-teaching... (1 Reply)
Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

Hi,
Will following set up work in bash script? I've got errors if assigning following binary command to a variable. But on the other hand, COMMAND="ls" works. Any explanation please? How can I assign binary command to a variable COMMAND then I can just call ${COMMAND}?

let me be specific. here's my code:
# URL port Variables

bf_tar
BF_TAR(1)BF_TAR(1)NAME
bf_tar - shell script to write a tar file of a bogofilter directory to stdout
SYNOPSIS
bf_tar [-r] [-R] bogofilter_directory
DESCRIPTION
bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
EXAMPLES below).
OPTIONS
The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
files.
The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.
EXIT STATUS
The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.
EXAMPLES
o bf_tar ~/.bogofilter > outfile.tar
Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.
o bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz
Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.
o bf_tar `pwd`/mydirectory > outfile.tar
Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.
NOTES
This script is meant for use with Berkeley DB based bogofilter versions.
This script requires a SUSv2 compliant pax utility.
This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
that /usr/xpg4/bin/sh can be used.
