cat /etc/passwd | cut -d: -f1,5 | sed s/:/" "/g

“s/” denotes the replace the next thing the “:” shows what to replace, then the “ ” shows what to replace with and the /g at the end means replace all instances on the line, not jus tthe first one. so that will basically change all colons to spaces on any lines returned.
