Search and replace in multiple files

I had a situation where , I need to replace a word with 'replace' in 181 xsd files. where I used following simple command.

search string : types.xsd
replace string : common/types.xsd

command inside the directory conain files :

perl -pi -e 's/types.xsd/common\/types.xsd/g' *.xsd

create 100 files in one command

Had a situation to create multiple xsd's in one location , i used following simple command .

"for (( i = 0 ; i < 100 ; i++ )) do touch $i.xsd; done;"

Kill all tomcat instances running by one command

kill -9 `ps ax | grep tomcat | grep -v grep | awk '{print $1}'`


You can improve this command to kill any process you want . just replace the 'tomcat'
with processor you want to kill .

changed files between two svn branch revisions

#!/bin/bash
#auther sanjeewaf
if [ ! $1 ] || [ ! $2 ] || [ ! $3 ] ; then
echo "Please enter a revision from, revision to, and SVN repository"
exit
fi

# set up nice names for the incoming parameters to make the script more readable
revision_from=$1
revision_to=$2
repository=$3

# the grep is needed so we only get added/modified files and not the deleted ones or anything else
# if it's a modified directory it's " M" so won't show with this command (good)
# if it's an added directory it's still "A" so will show with this command (not so good)

for line in `svn diff --summarize -r$revision_from:$revision_to $repository`
do
echo $line
done

# to summarize any deleted files or directories at the end of the script uncomment the following line
#svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[D]"
#eg : 20 25 svn://localhost/myrepository
