I am trying to print the name of directories whose free space is greater than zero.
#Listed all the directory and their consumed space.
du -sm storage*
365 storage1
670 storage2
1426 storage3
I have threshold value of 1000M , so I am trying to print free space in these directories relative to threshold value provided.
du -sm storage* | awk -v threshold="1000" '$1>0{print $1=threshold-$1,$2}'
635 storage1
330 storage2
-426 storage3
So , I want to print those directories whose free size is positive integer. Something like :
635 storage1
330 storage2
Any correction ?
I think this got overly complicated. If you just want to check that the size is positive and lower than a given threshold, say so:
awk -v threshold=1000 '0 < $1 && $1 < threshold'
$ cat file
635 storage1
330 storage2
-426 storage3
$ awk -v thr=1000 '0 < $1 && $1 < thr' file
635 storage1
330 storage2
