I've been tinkering with a shell script to partition and restore content to a drive based on a type of file in a given directory. My goal is for my script to assemble several restore images, partition the drive based on the images and to then restore those images to the partitions on the drive. Its going to be a multi-boot drive for troubleshooting different systems. Everything is going fine so long as the path to my "configuration" directory does not contain whitespaces.
Here is a snippet:
The result is unusable:
I've tried single and double quoting all over the place and I can't find the correct usage. All I'm looking for is this:
The "configuration" folder in my actual script is a variable passed on from another call earlier in the script. I know I could use:
but because the "/test folder" is a variable grepped from the output of a function that only gives human readable output, I'm stuck.
Thanks for any help - I've been working on this line of my script for 3 days now and I can't figure it out. I'm always in awe of how well some folks have mastered the command line. Thanks again!
I'm trying to find a command that will trim the white space off a string.
e.g.
$str = " stuf "
$str = trim ( $str )
echo $str // ouput would just be stuf
Thanks, Mark (4 Replies)
Hi,
I have been trying to remove whitespace from a file using sed. Here is an example of what im trying to do:
www1 = www1
www2 = www2
www3 = www3
and all the way to 300 and i want it to look like:
www1=www1
www2-www2
www3=www3
again upto 300
Any help... (12 Replies)
Hmmm... Bash doesn't parse whitespace with a read.
lev@sys09:~$ read line; echo "$line"
test
test
You can imagine what this does if you're using a shell script to read a list of unknown file names containing unknown spaces.
lev@sys09:~$ read word1 word2; echo "$word1,$word2"

it won't really work since some of the rows... (2 Replies)

checkbashisms
CHECKBASHISMS(1) General Commands Manual CHECKBASHISMS(1)NAME
checkbashisms - check for bashisms in /bin/sh scripts
SYNOPSIS
checkbashisms script ...
checkbashisms --help|--version
DESCRIPTION
checkbashisms, based on one of the checks from the lintian system, performs basic checks on /bin/sh shell scripts for the possible presence
of bashisms. It takes the names of the shell scripts on the command line, and outputs warnings if possible bashisms are detected.
Note that the definition of a bashism in this context roughly equates to "a shell feature that is not required to be supported by POSIX";
this means that some issues flagged may be permitted under optional sections of POSIX, such as XSI or User Portability.
In cases where POSIX and Debian Policy disagree, checkbashisms by default allows extensions permitted by Policy but may also provide
options for stricter checking.
OPTIONS --help, -h
Show a summary of options.
--newline, -n
Check for "echo -n" usage (non POSIX but required by Debian Policy 10.4.)
--posix, -p
Check for issues which are non POSIX but required to be supported by Debian Policy 10.4 (implies -n).
--force, -f
Force each script to be checked, even if it would normally not be (for instance, it has a bash or non POSIX shell shebang or appears
to be a shell wrapper).
--extra, -x
Highlight lines which, whilst they do not contain bashisms, may be useful in determining whether a particular issue is a false posi-
tive which may be ignored. For example, the use of "$BASH_ENV" may be preceded by checking whether "$BASH" is set.
--version, -v
Show version and copyright information.
EXIT VALUES
The exit value will be 0 if no possible bashisms or other problems were detected. Otherwise it will be the sum of the following error val-
ues:
1 A possible bashism was detected.
2 A file was skipped for some reason, for example, because it was unreadable or not found. The warning message will give details.
SEE ALSO lintian(1).
AUTHOR
checkbashisms was originally written as a shell script by Yann Dirson <dirson@debian.org> and rewritten in Perl with many more features by
Julian Gilbey <jdg@debian.org>.
