hi.... i am using the command (for D in /; do wc -l ${D}/ > ${D%/}Request;done) for word count but the problem is now it read all files in the particular directory .I want to read only .CUD files . Please suggest
NOTE: i have multiple directory, all directory contains .cud and .cur files. here i want data(no of lines) which are in .cud files only

please suggest...!!!!

Code:

for D in /; do wc -l ${D}/ > ${D%/}Request;done

for D in / will process a single file, namely /.

You need to generate the list of all your CUD files, then run wc on them. E.g.

Code:

wc -l $(find / -name ‘*.CUD’)

This will fail if there are too many CUD files. A better way is building the wc command into find, for example

Code:

find / -name ‘*.CUD’ -exec wc -l {} +

The strange string {} indicates the file that was found.

wc -l counts new lines, not words (see switch -w for that purpose)
Are you really sure your command is working?? As said by berndbausch this for loop only processes one file, namely "/"...

It would help if you properly specified your requirement.

hi used the command ==>> for D in /; do wc -l ${D}/ > ${D%/}Request;done which is working fine . But in each directory there are two file named as .CUD and .CUR , I want to read both files separately . Please suggest

and now in this thread

Try running this command in the top directory under which are all .CUD files to be interrogated.

Code:

( shopt -s globstar; for f in **/*.CUD; do wc -l "$f"; done )

The parentheses are important, to force the command to run in a subshell.
It is still unclear how you want the output; individual files in the directories containing the .CUD files or one file containing all results.
