“touch” is a unix command used to change the time of a file or directory, touch a directory will not touch the files inside.
To touch recursively, it’s simple with the help of “find” and “xargs”:
e.g.
find . | xargs touch
will touch all files and directories recursively under current directory.
Since directory or filename may contain spaces, the shell script need some additional parameteres:
find "$1" -type f -print0 | xargs -0 touch

In one of my project I need to replace some kind of strings in hundreds if file, the code paste here is for specific usage, but it could be easily changed to do something else.
It will scan all *.xml files in current directory and in sub directories, replace the value of two attributes to a big value.
| #!/bin/bash |
| # Get List of Files to Be Replaced |
| file_list=`find . -name ”*.xml” -type f` |
| # Define Target String to Be Replaced & Destination String for Substitution |
| echo ” Replacing *.xml file’s timeout to a big value ” |
| # Perform Substitution |
| for fn in $file_list |
| do |
| if ( test $fn != ./`basename $0` ) |
| then |
| ffnt=”$fn.temp” |
| echo ”Processing $fn …… ” |
| sed ’s/responseReadTimeout=”[0-9][0-9]*”/responseReadTimeout=”999999″/g’ $fn > $ffnt |
| sed ’s/socketReadTimeout=”[0-9][0-9]*”/socketReadTimeout=”999999″/g’ $ffnt > $fn |
| rm $ffnt |
| echo ” Done ” |
| fi |
| done |
