How to delete write protected file
Reader Ashish asks “How to delete write protected file under Linux…”
Under Linux (and other Unixsh oses) following criteria should matched before deleting a file:
Criteria # 1
To delete or remove a file you need to be owner of a file. Use ls -l command to verify your ownership:
$ ls -l filename
If you have sufficient rights, you can remove a file. Otherwise, become a superuser to remove a file.
Criteria # 2
In addition, you must have a write access to on a directory that allows you to remove or add new files. Again us ls -l or ls -ld command to get write ownership of directory.
$ ls -ld dirname
If you have sufficient rights, you can remove a file. Otherwise, become a superuser to remove a file. Use chown / chmod commands to setup permission OR run rm command as root user:
# su -
# rm -f file.txt
