[SOLVED] sed: Extract version number from string

Issue

Input: adcheck (CentrifyDC 4.4.3-421)

Desired output: 4.4.3

What I thought would work:

/usr/share/centrifydc/bin/adcheck --version | sed -n '/Centrify DC /,/-/p'

But that outputs nothing??

Thank you!

Solution

sed 's/[[:alpha:]|(|[:space:]]//g' | awk -F- '{print $1}' <<< "(CentrifyDC 4.4.3-421)"

output: 4.4.3

Using [:space:] to remove extras spaces.

sed is used to remove unwanted characters and awk -F- means use - as field separator
