Some cool Linux command I have learned this week:
Do you want some command run continuously for example every 1 sec?
bash
watch -n 1 "ls -1 | wc -l" #1
watch
Every one second it will run command written inside ""
ls -1
: Lists the items in the directory, one item per line.
|
: Pipes the output of the ls -1 command to the next command.
wc -l
: Counts the number of lines
How about checking the disk size?
df -h #2
What if I want to know the specific directory size?
du -sh *
I can also sort the output with sort
command in human readable way
du -sh * | sort -h
I can pipie above output to another command that will display only needed number
du -sh * | sort -h | head -n 2 # only 2 items will be shown
