# Search for occurrences of a simple string in all the files with a # given extension anywhere in a directory tree. # Copyright (c) 1990-1992 by Hamilton Laboratories. All rights reserved. # ts works by pushing the directory to be searched onto the directory # stack making it the current disk and directory. ls and grep are used # to recursively list all files (not directories) any where in the tree # that end with .ext where ext is whatever the caller requests. Assuming # there are some files, fgrep is used to search them, ignoring character # case and showing line numbers. The test is needed since calling fgrep # without a filename argument would cause it to try to read stdin. The # text argument is inside double quotes in case the search text is more # than one word. proc ts(startdir,ext, text) pushd -s $startdir set files = `ls -rD1 | grep -i \.$ext^$` if (files != '') fgrep -in "$text" $files | more popd -s end ts $argv
