Error while getting disk usage of a folder in unix

Question

I have XYZ=/opt/Ind and certain directories under /opt/Ind

I sorted the directories by : ls -t $XYZ Then I need to get only the size of the first folder. I tried

du -sk $(ls -t $XYZ/TAL/ | head -n 1)

It gives me this error

du: cannot access `\033[0m\033[01;34m20160525_033732\033[0m': No such file or directory

Will be glad for the help.

The problem here is that you are not using the normal ls but an alias, so that it provides you some coloured output. This way, instead of a normal name 20160525_033732 you get it with the blue colour.

$ echo -e "\033[0m\033[01;34m20160525_033732\033[0m"
20160525_033732

Just use \ls to use the original ls without any alias.

du -sk "$(\ls -t $XYZ/TAL/ | head -n 1)"
#         ^

See what the alias is with:

type ls

It will probably return something like:

ls is aliased to `ls --color=always'

Can I print only the size and not the folder name with this command – Mohit Arora May 27 '16 at 07:38
@MohitArora sure. You can say `du file | awk '{print $1}'`. – fedorqui May 27 '16 at 07:54

add --color=never to the ls so it won't colorize the output:

du -sk $(ls --color=never -t $XYZ/TAL/ | head -n 1)
