Shell Programming and Scripting

Hey,

I'm trying to install a java web archive on unix but all the jsp's are in windows text format. I need to convert them all to unix text at once but I really don't want to do that on a file per file basis so I need to loop over all text files in all subdirectories and change the ^M. Does anyone how to do that? I'm new to unix shell scripting and I can't get it to work myself.

Thankx.

There are a few ways to do this. Probably the easiest is with the dos2unix command (dos2ux on some systems)

so...

Code:

for file in /my/path/*
do
  dos2unix $file
done

You could also do it using tr

Code:

for file in /my/path/*
do
  tr -d '\r' < $file > $file.new
  mv $file.new $file
done

I changed it to:

#!/usr/bin/ksh
for file in /opt/hpws/tomcat/webapps/jcvsweb/*
do
if [[ -f $file ]]
then
tr -d '\r' < $file > $file.new
mv $file.new $file
fi
done

to make sure it only processes text files and not directories and binaries, which it seemd to do. It only goes one level deep. Is it possible to process all files in all subdirectories?

find /path/to/files -type f -exec dos2unix {} \;
-or-

Code:

find /path/to/files -type f -print | while read file
do
  # add further type testing here
  echo "Converting $file"
  tr -d '\r' < $file > $file.new
  mv $file.new $file
done

This is untested but should work
