In Perl I can write a condition that evaluates a match expression like this:
if ($foo =~ /^bar/) {
do blah blah blah
}
How do I write this in shell? What I need to know is what operator do I use? The '=~' doesn't seem to fit. I've tried different operators, I browsed the man page for... (3 Replies)
Hi,
I have a variable in my script that gets its value from a procstack output. It could be a number of any length, or it could just be a '1' with 0 or more white spaces around it. I would like to detect when this variable is just a 1 and not a 1234, for example. This is as far as I got:

Hi
Consider the file
this is a good line
when running
grep '\b(good|great|excellent)\b' file5
I expect it to match the line but it doesn't... what am i doing wrong??
(ultimately this regex will be in a awk script- just using grep to test it)
Thanks,

rename - renames multiple files
SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr argument is a Perl expression
which is expected to modify the $_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the
expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the extension, you might say
rename 's/.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
OPTIONS -v, --verbose
Verbose: print names of files successfully renamed.
-n, --no-act
No Action: show what files would have been renamed.
-f, --force
Force: overwrite existing files.
ENVIRONMENT
No environment variables are used.

If you give an invalid Perl expression you'll get a syntax error.
BUGS
The original "rename" did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin
Barker).
