red hat command displays very differently on centos7

hi guys

busy reading some material on RHEL7 and im doing exercises and notes etc on a centos7 machine

one command is:
ps -eafxo pid,user,cgroup,args | sort -nk1

in the book their are four neat columns

but when i run the command on my centos7 box i get a lot of garbled information that does make some sense but it almost looks encrypted or something...is this just because of a slight difference between the two OS's...?

It should work just the same, the problem is likely that the output in the example material is trimmed down. The "args" field in that command will print ALL arguments to a command, which for things like ssh, bash, web browsers, etc. can be a LOT and will quickly make the output look like gibberish.

you will definitely want to pass that to "less"

or

increase the bash output lines

i think the default is 1024 lines
i set it to 4096 lines

edit your bash user profile
" edit current profile"
