D="$(date "+%F %T.%N")"; [COMMAND]; find . -newermt "$D"

List all files modified by a command

Often you run a command, but afterwards you're not quite sure what it did. By adding this prefix/suffix around [COMMAND], you can list any files that were modified. . Take a nanosecond timestamp: YYYY-MM-DD HH:MM:SS.NNNNNNNNN date "+%F %T.%N" . Find any files that have been modified since that timestamp: find . -newermt "$D" . This command currently only searches below the current directory. If you want to look elsewhere change the find parameter, e.g. find /var/log . -newermt "$D"
Sample Output
./logfile.txt

Yes and no. lsof is great for commands that are *running* and have files open. This command shows what an already-finished command did.
