Chmod calculator
Convert Unix file permissions between octal, symbolic and chmod notation, with a checkbox grid and umask.
Octal (755, 0644, 4755), symbolic (rwxr-xr-x, drwxr-sr-x) or chmod syntax (u=rwx,g=rx,o=, a+x).
Try:
- Octal
- 755
- Symbolic
- rwxr-xr-x
- ls -l styleregular file
- -rwxr-xr-x
- Command (octal)
- chmod 755 file
- Command (symbolic)
- chmod u=rwx,g=rx,o=rx file
- Meaning
- Owner can read, write and execute. Group can read and execute. Others can read and execute.
- umask (directories)New directories start from 777.
- 022
- umask (files)New files start from 666, so umask can never give them execute bits.
