Top Forums Shell Programming and Scripting How to use sed to search a particular pattern in a file backward after a pattern is matched.? Post 302834405 by rajamadhavan on Friday 19th of July 2013 01:15:03 AM

$0 ~ pat will be true only when awk approaches the line containing 1172c1172. Thats when the script prints the previously saved path string (variable 'a') and exit. I hope you can get this.

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1). All options specified are passed directly to cmp(1) or diff(1). If only one file is specified, then the files compared are file1 (which must have a suffix of a supported compression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncompressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp(1) or diff(1) is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2011-03-19 XZDIFF(1)
