Homework and Emergencies Homework & Coursework Questions Display usernames and their UIDs Post 303018041 by MadeInGermany on Sunday 27th of May 2018 05:41:11 PM

From the given relevant commands I think the teacher or the course makers want to just cut one item from the passwd, process it in a for-do-done loop, and in the loop grep the item in the passwd again in order to get the second item.
But this is less efficient compared to piping the pair of items to awk or a while read loop.
The latter can directly split into variables if the field separator IFS is set accordingly. You do not even need to run cut before.
