This can avoid big mistakes as this I just made. I thought I could give it an argument. So, now, it is possible.

### Aliases
|
|
|
|
# Set all files' permissions to 644 recursively in a directory
|
|
set644() {
|
|
find "${@:-.}" -type f ! -perm 644 -print0 | xargs -0 chmod 644
|
|
}
|
|
|
|
# Set all directories' permissions to 755 recursively in a directory
|
|
set755() {
|
|
find "${@:-.}" -type d ! -perm 755 -print0 | xargs -0 chmod 755
|
|
}
|
|
|
|
### Functions
|
|
|
|
# fixperms - fix permissions on files and directories, with confirmation
|
|
# Returns 0 on success, nonzero if any errors occurred
|
|
fixperms () {
|
|
local opts confirm target exit_status chmod_opts use_slow_mode
|
|
zparseopts -E -D -a opts -help -slow v+=chmod_opts
|
|
if [[ $# > 1 || -n "${opts[(r)--help]}" ]]; then
|
|
cat <<EOF
|
|
Usage: fixperms [-v] [--help] [--slow] [target]
|
|
|
|
target is the file or directory to change permissions on. If omitted,
|
|
the current directory is taken to be the target.
|
|
|
|
-v enables verbose output (may be supplied multiple times)
|
|
|
|
--slow will use a slower but more robust mode, which is effective if
|
|
directories themselves have permissions that forbid you from
|
|
traversing them.
