asked on
script to delete a line in a file based on a pattern
I have a requirement to compare the file contents in two different directories..
Dir One
Test.java
Abc.java
Dir two
Test.java
Abc.java
before comparing the files for differences, I would like to delete few lines in these files,
for example, these files have CVS repository information on the top
Source: $Source: /home/test/blah$
Module $abc$
can some one provide a script to delete these lines based on a given pattern in all the files in a directory.
Once those lines are deleted, I will use a dircmp command to perform the diff on the directories..
thanks

#!/bin/bash
for F in `find /full-path-to-top-dir -type f`
do
cd `dirname $F`
FILE=`basenmae $F`
awk ' !/^Source:/ || !/^Module/ {print}' $FILE > ${FILE}_new
/bin/mv -f ${FILE}_new $FILE
done
Where say your files are under /home/cvs/work, then replace /full-path-to-top-dir to /home/cvs/work

thanks for the quick response, however, the awk command is not replacing the lines that are starting with Module or Source
i have this file
Test.txt
Line 1
Line 2
Module
Source
I run the following
FILE=Test.txt
awk ' !/^Source:/ || !/^Module/ {print}' $FILE
it doesnt seem to be deleteing those lines, can you cross check?
