Hi ,
I have a requirement to append file creation date to each row in a file for all the files in a directory.
Please help
Thanks,
Pavan
Although some filesystems do have a file creation timestamp, most do not. The standards only require three timestamps for files (last access timestamp, last data modification timestamp, and last status change timestamp). Many people incorrectly refer to the last status change timestamp as the file creation timestamp, but it is marked for update to the current time not only when a file is first created but also whenever the size of the file changes, the mode of the file changes, or the ownership of the file changes.
By default ls -l displays the last data modification timestamp, ls -lu displays the last access timestamp, and ls -lc displays the last status change timestamp.
Allowing for Don Cragun's caveat and using his approximation, you can try
awk 'FNR==1 {("stat -c%z " FILENAME) | getline t; split (t, T)} {print $0, T[1]}' *
