Bash/Linux Sort by 3rd column using custom field seperator

Question

I can\'t seem to sort the following data as I would like;

find output/ -type f -name *.raw | sort 
output/rtp.0.0.raw
output/rtp.0.10.raw
output/rtp.0.11.raw         


        

Answer 1

This makes it:

$ sort -t'.' -n -k3 a
output/rtp.0.0.raw
output/rtp.0.1.raw
output/rtp.0.2.raw
output/rtp.0.3.raw
output/rtp.0.4.raw
output/rtp.0.5.raw
output/rtp.0.6.raw
output/rtp.0.7.raw
output/rtp.0.8.raw
output/rtp.0.9.raw
output/rtp.0.10.raw
output/rtp.0.11.raw
output/rtp.0.12.raw
output/rtp.0.13.raw
output/rtp.0.14.raw
output/rtp.0.15.raw
output/rtp.0.16.raw
output/rtp.0.17.raw
output/rtp.0.18.raw
output/rtp.0.19.raw
output/rtp.0.20.raw

As you see we need different options:

• -t'.' to set the dot . as the field separator.
• -n to make it numeric sort.
• -k3 to check the 3rd column.

Update

This also makes it:

$ sort -t'.' -V -k2 a
output/rtp.0.0.raw
output/rtp.0.1.raw
output/rtp.0.2.raw
output/rtp.0.3.raw
output/rtp.0.4.raw
output/rtp.0.5.raw
output/rtp.0.6.raw
output/rtp.0.7.raw
output/rtp.0.8.raw
output/rtp.0.9.raw
output/rtp.0.10.raw
output/rtp.0.11.raw
output/rtp.0.12.raw
output/rtp.0.13.raw
output/rtp.0.14.raw
output/rtp.0.15.raw
output/rtp.0.16.raw
output/rtp.0.17.raw
output/rtp.0.18.raw
output/rtp.0.19.raw
output/rtp.0.20.raw

As you see we need different options:

• -t'.' to set the dot . as the field separator.
• -V to make it sort based on version.
• -k2 to check the 2nd column.
