Keep track of diff progress

lsof -c diff -o -r1 | grep $file
When running a long `diff -r` over folders, this simulates a "verbose" mode where you can see where diff is in the tree. Replace $file with the first part of the path being compared.

  • You're running a program that reads LOTS of files and takes a long time. But it doesn't tell you about its progress. First, run a command in the background, e.g. find /usr/share/doc -type f -exec cat {} + > output_file.txt Then run the watch command. "watch -d" highlights the changes as they happen In bash: $! is the process id (pid) of the last command run in the background. You can change this to $(pidof my_command) to watch something in particular. Show Sample Output
