Shell Programming and Scripting

let me clarify again.. my intention is whenever a logfile gets modified, attach the modified timestamp and store the file into the same dir so that it will not overwrite the old ones. I need it in numerical form for some other manipulations later.. hope this clarifies..

you can try something like

Code:

ls -l filename
-rwxr-xr-x   1 root         other         29 May  8 10:07 filename

cp filename filename.`ls -l filename|awk '{print $8$6$7}'`

ls -l filename*
-rwxr-xr-x   1 root         other         29 May  8 10:07 filename
-rwxr-xr-x   1 root         other         29 May  8 10:07 filename.10:07May8

just noticed your remit, its not all the way there but a start

Thanks tag..
Bt I may want to hav the timestamp completely in numberformat..
I have heard of some option called -mtime.. will it help me here?

try this

ls -l --time-style=+%Y%m%d%H%M%S | awk '{print $7$6}'

Hi.. I am not sure whether u r using some other flavours of Unix. In AIX i dont get the out put of ls in number format as u... i mean the month will be in letters . Also when i try to run this cmd

ls -l --time -style=+%Y%m%d%H%M%S | awk '{print $7$6}'

its giving me error..

$ ls -l --time -style=+%Y%m%d%H%M%S | awk '{print $7$6}'
