Hi,

I have noticed that rm -if will perform completely different to rm -fi. Whats the pattern of how I put my options to the script in relation to how it will act.

i.e

rm -fi treat the...

Its ok, i totally understand it now, thank you for all your help. Its a little tricky programming in this single looping manner of awk when youve never done it before.

But actually it will make...

Ok, still not understanding.

You said:



what do you mean "in the array". The first field of the line will be the UID, lets say its 25. Well none of the entries in the array will be "25",...

vgersh99, im about 3/4 the way to understanding what your saying. Im going to read and re-read this but i may be back so dont go anywhere :-)

Think its primarily this I am having problems with:

arr[$1] = ($1 in arr) ? arr[$1] SUBSEP $0 : $0

I just dont know what its saying to me

vgersh99, thats almost exactly what I wanted. The only problem is I dont have a clue what youve done there :-). Could you possibly talk me through some of this.

shereenmotor, actually the example of ps -ef i gave showd the UID as root, which may make you think that later down the list it would give the other names. But it actually give the ID for the users...

Ok basically i want to write a script that outputs something like this:

(for each user)
Username
PID TTY Time CMD
(end for each)

so i.e.

James.Brown

PID TTY ...

shereenmotor ive not put all of the results but you get the idea:

ps -ef:

UID PID PPID C STIME TTY TIME CMD
root 1 0 0 May26 ? 00:00:07 init
root ...

Basically:

ps -ef

This gets me all the information I need except the username. Though it does return the users ID (UID). I need to know how I reference the username from the UID.


Thanks,...

shereenmotor: ps -ef doesnt output the username at all, it does however output the UID, which still doesnt help because I need to link the UID to a username.

grial: ps -O will work, but i dont...

Hi All,

I am trying to write a script to list all users and their processes. I cant seem to find out how to link the PID to the user. For example if i run ps -a I get a nice list of all the...

ahhh, thanks chief.

lol, im back :-). I have no problems printing the results to the screen but i can seem to add them to a file i.e.

for(j=1;J<=i;j++)
{
print Lines[j] > Out
}

Gives me this error:

awk:...

nevermind just did

for(j=0;J<i;j++)
{
print Lines[j]
}

Ta Chris.

Actually i have another problem, i didnt actually want to print the line to out put i wanted to save it as an array and print at the end i.e.

BEGIN
{
i=0
}
{
i++
Lines[i]= i ")" $0
}
END...

Thanks vgersh99, knew it would be something simple. And ill take a look at printf.

Thanks again, Chris.

Hi All,

I know that i can print the lines from awk just using the print method, but i need to print stuff before it i.e:


BEGIN
{
i=0
}
{
i++
print i ")"
print
}
END
{
}

Here the...

Thanks sssow thats what I was after.

How do i in a script determine the user that is executing it?

Thanks all

Sorry, i thought the new line was accidental.

Your script shows at the end:

"Your Text Goes here, dont use variable here' NewFile"

How would I use a variable there then? As I said I wanna...

Actually, can someone just show me a simple sed command for adding "Hello" to a file called "MyFile" at line 5. Forget the scripts just a single command to add the word hello at line 5.

Thanks,...

Hi Shereenmoter,

I got exactly the same error:

sed: -e expression #1, char 3: Extra characters after command

This is what ive written so far:


#Get the number of lines in the file...

I keep getting this error when i try to run the script:

sed: -e expression #1, char 3: Extra characters after command
