Full Discussion: grep for greater than 12 chars
Top Forums Shell Programming and Scripting grep for greater than 12 chars Post 302310930 by bakunin on Monday 27th of April 2009 11:00:38 AM

I assume the customer number is really a number, constructed from digits 0-9, yes?

If so, try the following regexp:

Code:
grep '[0-9]\{13\}' /path/to/file

This will find all lines containing a sequence of 13 or more digits.

I hope this helps.

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.
