I've recently written a BASH function for auto completion of options. It works like following: if a user types a command and then an argument to this command which starts with "^-" and then presses TAB, then 'user_command --help (or -h)' is invoked and possible options are retrieved form the program's help and suggested as possible completions. Simplified it looks like:
But I have a little problem, I want to make my function a little bit cuter. I want to add white spaces to the completed option if it doesn't end with "=" sign, and vice versa not to add white space if auto completed option ends with "=". It could be done by supplying '-o nospace' to 'complete'. But I don't want that this affects auto completions of other arguments (which don't start with '^-') for those arguments white spaces shall be added in the regular way.
Thanks in advance for your help. Write to me, if you didn't understand my problem. I'll try to describe it better
How would I delete white spaces in a specified file?
Also, I'd like to know what command I would use to take something off a regular expression, and put it onto another.
ie.
.
.
.
expression1 <take_off>
.
.
.
expression2 (put here)
.

Any help would be great, thanks! (10 Replies)

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
