Less known but useful bash Commands
Less known but useful Commmands
Redo last command but as root
sudo !!
Open an Editor, write a bash command
(and execute in shell)
ctrl+x+e
Create superfast Ramdisk
mkdir -p /mnt/ramm
mount -t tmpfs tmpfs /mnt/ram -o size=8192M
fix a really long command
(that you messed up)
fc
quickly create folders
mkdir -p folder/{sub1,sub2}/{sub1,sub2,sub3}
exit terminal but leave all processes running
disown -a && exit
fdupes
delete duplicate files without conformation
fdupes -r /path/to/folder
To manually confirm deletion of duplicated files
fdupes -r -d /path/to/folder
To automatically delete all copies but the first of each duplicated file
(be warned, this actually deletes files, as requested)
fdupes -r -f . | grep -v '^$' | xargs rm -v
I'd recommend to manually check files before deletion
1. write duplicates to text-file
fdupes -rf . | grep -v '^$' > files
2. then manually check the files to delete and remove files that should not be deleted from file 3. remove all files that occour in the text-file with:
xargs -a files rm -v
