UNIX for Dummies Questions & Answers

This should work:

Code:

find /path/to/dir/* ! -name . -prune -type f -ls

How can we filter this command with .css file only and by date !!

You just add all the options you need as suggested before, such as the -name, -newer etc.

I would worry though that using /var/output/* as the place to search from might be expanded by the shell to a very long list and exceed the command line limit if there are lots of files in /var/output.

I agree Robin.

Personally I'd just yield to performing the task using a script myself, but that's just me. ;-)

There are still two problems with the current command.

Code:

find . ! -name . -prune -type f -name "*.css" -ls -mtime 7
9697084 4883 -rw-rw----   1 5000032 Dec 30 11:59 ./P010111.css
9464599 4883 -rw-rw----   1 5000032 Jan  8 09:04 ./P020367.css
8896700 4883 -rw-rw----   1 5000032 Jan  2 21:19 ./P013461.css
9404834 4883 -rw-rw----   1 5000032 Jan  8 14:12 ./P020427.css

A) I wanted files for 2nd Jan only. But it displays all .css files

The help for find told me to use mtime

B) The file names is displays as ./P010111.css instead of just P010111.css

There are other problems with this that you didn't mention. But, to get closer to what you wanted move the -ls primary after the -mtime primary:

Code:

find . ! -name . -prune -type f -name "*.css" -mtime 7 -ls
8896700 4883 -rw-rw----   1 5000032 Jan  2 21:19 ./P013461.css

But the files this lists will be files that are more than 6 * 24 hours old and less than or equal to 7 * 24 hours old at the time find starts; not files with dates between midnight at the start of the day and midnight at the end of the day on January 2, 2014.

If you want files with the date January 2, 2014 and you don't want the names to have the leading ./, you have several choices. Among them are:

Code:

#!/bin/ksh
trap 'rm -f $$.start $$.end' 0
touch -t 201401020000 $$.start
touch -t 201401030000 $$.end

printf "Using shell for loop:\n"
for i in *.css
do      if [[ "$i" -ot $$.end ]] && [[ "$i" -nt $$.start ]]
        then    ls -l "$i"
        fi
done

and:

Code:

#!/bin/ksh
trap 'rm -f $$.start $$.end' 0
touch -t 201401020000 $$.start
touch -t 201401030000 $$.end

printf "\nUsing find:\n"
find *.css -newer $$.start ! -newer $$.end -ls

Both of these scripts use features that are not defined by the POSIX Standards nor the Single UNIX Specifications. Although written using the Korn shell, the 1st script above should work with any ksh or bash shell.

The 2nd script may fail if *.css expands to a list of files that creates a find command line longer than your system's ARG_MAX limits or if the version of find on your system doesn't support the -ls primary.

If you just want a list of the file names (instead of long format ls output), change:

Code:

        then    ls -l "$i"

in the 1st script to:

Code:

        then    printf "%s\n" "$i"

and change:

Code:

find *.css -newer $$.start ! -newer $$.end -ls

in the 2nd script to:

Code:

find *.css -newer $$.start ! -newer $$.end

thank you so much !!
