I wanted to use grep to search some files containing code - and the result was very disappointing: although I could see with my own eyes the expressions (written in the files), grep didn't give any output.
Basically, I write this to the terminal
or
in a folder in which some txt files have the word Find in them. Some file also contain some variants like Find, ["Find"], ["FindAllChi..."], etc. I don't get any output, i.e. grep doesn't say file blablabla.txt contains Find or bla2.txt contains FindAllCh..
If I'm editing a file to contain just one line of code, grep finds what I'm looking for.
Can you give some suggestions on how to make grep working?
Thank you!

I am trying to run the following code from a script file but it complains that syntax of (both instances of) grep is wrong.
When I copy and paste it to the terminal, it is OK. Any idea what the problem might be?

how do i check a file for a pattern and perform an action if it doesn't exist?
i know how to search a file for a pattern. you just place it in an array like so.
#!/usr/bin/perl
my $data_file = "file.txt";
open DATA, "$data_file";
my @array_of_data = <DATA>;
if ($_ =~ m/pattern/i) {... (4 Replies)

Hi there,
the following script doesn't work. the first part works, then the second 'grep' fails with ': not found'. However, if I take out the second part (starting with the grep command) and put in a seperate script, it works.

Here's some sample output and my code follows it. Why can't find() find '|'. It just dosn't make a bit of sense at all.

Hi,
I'm trying to write a script that checks gvfs to see if a mount exists so I can run it from network-manager's status hooks. I thought I'd pipe the output of gvfs-mount -l to grep for the particular mounts I care about. When I do this in a bash script:

I ran the following grep and sed command.
grep "\t" emp.txt
sed -n '/\t/p' emp.txt
grep treated the '\' as to escape t and took the pattern as literal t whereas sed took the pattern as tab.
That means , grep doesn't understand escape sequence!!!!!!

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.
