script to change the access permissions of the files

Hi,
I want to change the access permissions of the files whose extension is same.For example *.c but these are inside a directory and inside that other directory is there and it contains the .c files..for example--

Quote:
I have main directory(src),inside that I have some directories(tools,test and others) and some *.c files
/src/tools/a.c
/src/tools/b.c
/src/x.c
/src/y.c
/src/test/p.c
/src/test/q.c
and so on other dir and files..
So my aim is to search the files under src and change the access permissions for all *.c files using the shell script..

Any reply will be appreciated...

No need for a shell script
Code:
find ./src -name '*.c' -type f -exec chmod 0644 '{}' ';'

Modify the path and permissions as needed.

I used the command
find ./src -name '*.c' -type f -exec chmod 0644 '{}' ';'

but files a.c & b.c inside /src/tools is unchanged...
ls -l
-rw-r--r-- 1 root other 2309 Jan 13 18:05 a.c
-rw-r--r-- 1 root other 2309 Jan 13 18:05 b.c

As I said, adapt the path and permissions as needed. So to change all files in the /src directory (and below) use
Code:
find /src -name '*.c' -type f -exec chmod 0644 '{}' ';'

(Notice the missing dot in frot of /src)
As for the "unchanged" permissions: a permission of 0644 (in octal) equals to -rw-r--r-- in the ls -l output. If you change it to 0640, ls -l would show permissions of -rw-r-----
