Example File

id : Print the current user's UID and GID.
id -u root : Find the UID of the user named "root".
id -g root : Find the GID of the user named "root".
id root : Find the UID and all groups associated with the user "root".
id -G root : Display the UID and all groups a user "root" belongs to.
id -ng root : Display the name instead of numbers for GID of "root".
id -nu root : Display the name instead of numbers for UID of "root".
id -nG root : Display the name instead of numbers for all groups of "root".
id -r -g root : Display the real GID instead of effective GID of "root".
id -r -u root : Display the real UID instead of effective UID of "root".
id -r -G root : Display the real group IDs instead of effective groups of "root".

Command

awk 'BEGIN {FS=":"} {print $1}' commands.txt | xargs -I command bash -c 'eval command'

Output

uid=1000(user) gid=1001(user) groups=1001(group),24(cdrom),25(floppy),27(sudo),29(audio),30(dip),44(video),46(plugdev),106(netdev),114(bluetooth),117(lpadmin),120(scanner),993(bumblebee),1000(docker)
