Muppet Newbie terminal command questions

Q_Ball

Guys i've been searching the web looking for these commands but i cant find them so i'm hoping someone here can help.

1) How do you display the PATH and ls -l commands in a more "user friendly" way? such as permissions and mod times etc

2) How do i display a summary of disk usage for each diretory argument? I will figure out how to format in bytes KB and Mb myself. Also does that imply that the user must enter a diretory?

And the most embarassing one of all.......

3)What arguments of the who command only show those in your group?

Cheers

1) don't quite know what you mean.. if you mean a file explorer type interface, have a look at installing "midnight commander" .. otherwise pipe the output of ls to sort (ls -al |sort) and if you want to display the path then have a look at simply editing your prompt to include the current path (have a look in .bashrc .zshrc or .cshrc depending on what shell you are running)...

2) du -k

3) no idea offhand.. i cant recall any switch for w/who or finger that displays users groups.

ssh

You aren't by any chance in 2nd year CS in DIT, are you? :-)

1)
echo $PATH | sed 's/:/\
/g' | while read line; do
ls -plahd $line
done

2) du -h will tell you the usage of a directory, the -h makes the numbers more readable.

3) they don't exist. You need to use groups command to find which groups you are in, one per line, preferably.

then
who | cut -d " " -f 1 |
while read user; do
groups $user | grep ${mygroup[0]}....
done

that won't work, coz it's incomplete, but that's the general idea.
