[SOLVED] looking to convert first name last name to first initial last name from a getent output

Issue

I have to convert this.

getent passwd euser5
euser5:x:12345:20:Ester Jones:/home/euser5:/bin/csh

so far i have this.

getent passwd euser5|cut -d: -f1,5 |sed 's/:/,/'|tr '[:upper:]' '[:lower:]'
euser5,ester jones

the final output i need is

user5,ejones

Solution

Using sed

$ sed -E 's/:[^ ]*:(.)[^ ]* ([^:]*).*/\L,\1\2/' <(getent passwd euser5)
euser5,ejones
