Ls ignoring files from their modification time
Hi everyone,

I'd like to know if is there a way to list files but ignoring some according to their modification time (or creation, access time, etc.) with the command 'ls' alone.

I know the option -I exist, but it seems to only looking in the file name..

Thank you in advance for the answers.

P.S : Ftm, I'm transferring the result of 'ls' to awk (by pipe ofc)..maybe there is a more elegant way to do so..

awk
Hi,

Try this out,

Code:
#! /usr/bin/bash
for file in *;
do
   if [ -d "${file}" ];
   then
      echo "${file} is a Directory"
   elif [ -s "${file}" ];
   then
     awk 'END{print FILENAME;}' ${file}
   else
      echo "${file} is unknown file type"
   fi
done

I think the loop around the awk is the best idea with *(excludes spaces in file name issue).
I just wrote some simple example.
Please modify the code based on your req.

Cheers,
RangaSmilie

find could be better choice for you.
look for -newer, -older, -mtime, -atime, -ctime options under that.

Yes, I thought about find , the problem is that I have something like 1000 folders, and in each there are something like 200 files...And I'm only looking for one..

I tried to optimize find..but it's way way longer than ls..

I doubt it!

Please post what Operating System and version you are running and what Shell you are using. There is much variation in the ls command and as much variation in the find command.

Please state what your criteria are for selecting files.


(Please avoid using textspeak or obscure abbreviations when posting. Ftm? ofc?).

Not quite sure how the script addresses the original post. The script posted contains a couple of bugs and some excess semi-colon characters. Notably it did not deal with filenames containing spaces or files of zero length.

Code:
#! /usr/bin/bash
for file in *
do
   if [ -d "${file}" ]
   then
      echo "${file} is a Directory"
   elif [ -f "${file}" ]
   then
     awk 'END{print FILENAME;}' "${file}"
   else
      echo "${file} is unknown file type"
   fi
done

How would find checking every single file, be slower than ls checking every single file?
