for file in *.mp3; do eval $( id3tool "$file" | sed 's/^[^:]* //; s/:[\t ]*/="/; s/[[:cntrl:]]//g; /./!d; s/ *$/"/' ) { [ "$Artist" -o "$Album" ] && dir="$Artist/$Album/" ; } || { [ "$Artist" ] && dir="$Artist/" ; } || continue mkdir -p "$dir" ; mv "$file" "$dir/" done
It uses id3tool to read the ID3? tag, instructs SED to massage the information into something that looks like Shell script, executes that to put values into variables, checks which variables are set, and if at least an artist name (optionally also album name) is given, moves the file into that directory. (It's rather a mouthful for a oneliner, but hey.)
for uid in $( gpg --with-colons --list-keys | grep ^pub | awk -F: '{print $5}' ) ; do gpg --refresh $uid ; sleep 5 ; done
Alter the number after sleep(1) to change the speed of the refresh. This is equalivent to the slightly more understandable:
for uid in $( gpg --with-colons --list-keys | grep ^pub | awk -F: '{print $5}' ) ; do gpg --refresh $uid sleep 5 done
This is a useless use of grep. Better written as follows:
for uid in $( gpg --with-colons --list-keys | awk -F: '/^pub/{ print $5 }' ) ; do gpg --refresh $uid ; sleep 5 ; done
which can be abbreviated as
gpg --with-colons --list-keys | awk -F: '/^pub/{ print $5 }' | xargs -ri sh -c 'gpg --refresh {} ; sleep 5'
It's a pity xargs(1) doesn't offer any speed controls itself, in that case the ugly roundabout via shell wouldn't be necessary.
