But this assumes that the option was*not* already on when we entered
the function. If it was on, we've just turned it off. Another way to
do this, which doesn't permanently alter the option for the remainder
of the shell's lifetime, would be to wrap the function body in a subshell:
duhs() {
(
shopt -s dotglob
printf '%s\0' "${1:-.}"/*/ | xargs -0 du -sh
)
}
I've some issue with this function. It doesn't show the size of the
directory specified as argument, it follows the output of my original
function:
duhs1() { IFS=$'\n\r' ; for d in $(/usr/bin/find $1 -maxdepth 1 -type d
|/usr/bin/sort) ; do du -hs $d ; done }
~# duhs1 /usr/local/
88K /usr/local/ ←←←
4,0K /usr/local/bin
4,0K /usr/local/etc
...
According to the very kind Greg's explanation I tried to change the
function in this way:
duhs() {
(
shopt -s dotglob
du -sh "${1:-.}"
printf '%s\0' "${1:-.}"/*/ | xargs -0 du -sh
)
}
the specified directory is shown, but the output has became messed up:
~# duhs /usr/local/
88K /usr/local/
4,0K /usr/local//bin/
4,0K /usr/local//etc/
4,0K /usr/local//games/
4,0K /usr/local//include/
4,0K /usr/local//man/
4,0K /usr/local//sbin/
56K /usr/local//share/
4,0K /usr/local//src/
and worst the size of /usr/local/share isn't 56K:
~# du -hs /usr/local/share/
60K /usr/local/share/
as it's shown by my original function:
~# duhs1 /usr/local/
88K /usr/local/
4,0K /usr/local/bin
4,0K /usr/local/etc
4,0K /usr/local/games
4,0K /usr/local/include
4,0K /usr/local/sbin
60K /usr/local/share
4,0K /usr/local/src
the /usr/local/man/ isn't listed by the "find" command because it's a
symlink:
~# ls -l /usr/local/man
lrwxrwxrwx 1 root root 9 21 giu 2023 /usr/local/man -> share/man
Is there a way to have duhs() function that it doesn't print a double
"/" at the end of the specified directory?
The size mismatch of /usr/local/share could depend by /usr/local/man is
a symlink of 4K's size to a directory embedded in /usr/local/share, am I
right?
