bash-completion: Swap order of characters in egrep bracket expression
With glusterfs-cli installed, bash tab completion fails to work and prints an error message: $ gluster volgrep: Invalid range end ^C The problem is caused by the ordering of characters within an egrep bracket expression in the "_gluster_completion()" function defined in /etc/bash_completion.d/gluster. The file contains this line: egrep -ao --color=never "([A-Za-z0-9_-.]+)|[[:space:]]+|." | \ And egrep is interpreting the "-" character in that bracket expression as indicating a range is being requested, "_-." Fortunately, "_" actually comes after ".", this range expression is invalid, and egrep throws the error instead of silently not doing what was intended. The fix is simply to swap the positions of "-" and "." in that bracket expression: egrep -ao --color=never "([A-Za-z0-9_.-]+)|[[:space:]]+|." | \ With this change, bash tab completion works as intended.
