Shell Programming and Scripting

Hi everyone,

I want to know how to replace file extensions. For example how do i go about replacing all *.c files in a directory to *.cpp

I think we can do it either with "find" commad or with special registers. I tried to use the following command

mv \(.*\).c \1.cpp

but it is giving an error saying, cant stat source (.*).c
whats wrong with this ?

I am not sure how to do it with find commnad. please let me know if anyone of you know how to do it.

This will do the trick!

#Korn shell or Bash

for list in `ls -1t *.c*`
do
prefix=`echo $list | awk -F"\." '{print $1}'`
mv $list ${prefix}.cpp
done

Still requires multiple commands, but in the Korn shell, you can do

for file in *.c; do _file=${file%%.c}.cpp; mv $file $_file; done

on a single line, although it hampers readability....

That will rename all .c files to .cpp in the current directory.

Peace,

Hi Guys ...I found one other way of doing it. Try this

ls *.c | awk -F '.' '{print "mv "$1".c "$1".cpp"}'| csh

It does the trick. Thanks

lname=`basename $fname c`
mv $fname ${lname}cpp
