Top Forums Shell Programming and Scripting Script extract text from txt file with grep Post 302915383 by pilnet101 on Tuesday 2nd of September 2014 04:42:06 PM

The main two issues with your grep is that you are looking for a match at the beginning of the line (using ^). There is only one line which has data at the very beginning in your example text, which is the first line. Also you are only looking for two lower case characters.

If your requirement is essentially, look for a " then at least two characters, followed by all sorts of data (which may include a pipe) fololwed by a ) , then you can simply change your grep to:

Code:
grep '\"[a-zA-Z][a-zA-Z].*)'

Also just to add, you don't need the cat in there, you can simply pass the file to the grep command so the last line in your script becomes:

Code:
grep '\"[a-zA-Z][a-zA-Z].*)' somefile.txt > outputfile.txt

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. AUTHOR
