Top Forums UNIX for Dummies Questions & Answers how to use grep: finding a string with double quotes and multiple digits Post 302488565 by Chubler_XL on Monday 17th of January 2011 06:08:34 PM

If your grep supports -E (extended regex) then you can use
Code:
grep -E '"[0-9]{10}"' datafile

If not you will just have to repeat the char list 10 times:
Code:
gerp '"[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]"' datafile

If this is matching what you want, use the grep -v option to print all lines but those that match (in effect deleting the matching lines).

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...] zegrep [grep-flags] [--] pattern [file ...] zfgrep [grep-flags] [--] pattern [file ...] DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1). The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern argument. zegrep calls egrep(1), while zfgrep calls fgrep(1). EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0. SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1) AUTHORS
