Try this

The ls command has a couple of switches here that might accomplish what you are looking for. After reading this, do a man ls on whatever flavor of Unix you are using in case the exact letter used for the switch is different.

First, ls -lc will usually give you a timestamp of when the file was last modified.

Secondly, ls -lu will usually give you a timestamp of when the file was last accessed.

So, if a file has been created and never accessed (and hence never modified), an ls -lu command will report the timestamp of when the file was created. But the next time you access the file, that timestamp is updated.

Now, if you are trying to figure out which files are older than other files, you could try this:

ls -lct /directory

-l --> Gives the long listing, which includes the timestamp
-c --> Gives a timestamp of when the file was last written to
-t --> sorts the output so that the files most recently modified are at the top and the older modification times are at the bottom.

So, combining all of this with what I've gathered from your other posts:

from your home directory:
grep <whatever it is your looking for> /directory/of/*.dbf > somefile

Now, if you did a more on somefile the entry will probably look like this:
<the name of the file containing the string>:<the string you searched for>

Now, you want to get information on that file. If there are only a handful of lines, you could open somefile in vi and manually delete everything after the colon, which just leaves the filename. But, if you end up with dozens or even hundreds of entries, we need a more efficient way to parse out the filename.

awk -F: '{print $1}' somefile > somefile2
mv somefile2 somefile

We now have a list of all files in the /directory/of/*.dbf that match the string you wanted. Now to get information on those files.

for filename in `cat somefile`
do
ls -lc $filename >> somefile2
done
mv somefile2 somefile

Finally, more somefile.

** You'll note in my for loop I did not use the -t flag on the ls command. Since we're getting info on files one at a time, their really isn't a way to sort them here. Once we get all the output into a text file, you could use awk and sort to put them in order if you needed. **

It kinda long and ugly, but from what you told me this should get the job done.

Did this answer your question or did I go WAAAYYYY out in left field?

NAME
cg - Recursively grep for a pattern and store it. SYNOPSIS
cg [ -l ] | [ [ -i ] pattern [ files ] ] DESCRIPTION
cg does a search though text files (usually source code) recursively for a pattern, storing matches and displaying the output in a human- readable fashion. It is intended to give some of the functionaly of AT&T's cscope(1) tool, with the advantages of simplicity and not being language-specific. The script will colorize output if configured as such. It is typically run with a Perl regular expression to search for. The search can be made case insensitive by using the -i option. A list of files may also be specified with an additional argument after the pattern. Put the files pattern in quotes to make it be matched by Perl rather than by the shell. Running the script with no arguments will recall the results of the previous search. After the search, entries found can be edited using the vg(1) script. The -l option shows the last log made. SOME EXAMPLES
cg - alone recalls the previous search results. cg -i pattern - search the default list of files for all files matching the pattern (and case-insensitively). cg pattern '*.c' - search recursively for pattern in all *.c files. This automatically converts '*' to '.*' and '.' to '.' for you and does a Perl pattern match on all files in the tree. cg pattern *.c - search through the shell-expanded list of *.c files, so not done recursively (in other words, only the files your shell pass to the script as arguments). cg -l - show the last log made. COMMAND-LINE OPTIONS -i Do a case-insensitive search. -l Show the last log made. -p Toggle the default pager option. cg has a bulit-in pager function, which can be enabled or disabled by default (in .cgvgrc). If the default is enabled, this option disables the pager; if the default is disabled, this option enables it. -P Force the built-in pager to be disabled. FILES
${HOME}/.cglast Log file of the last search. ${HOME}/.cgvgrc Per-user configuration file (if the defaults are not desireable). ${HOME}/.cgvg/* Log files in $HOSTNAME.shell_pid form with the log of the last search. SEE ALSO
