Need Urgent Help!!!
Hi guys,
I have to write a script. the criteria is:
Create a script named 'userprocesses' which will allow you to find all users currently logged on to the system and display the processes they are running. The heading for each user must be their real name not their log in name.
I.e. my login name is furqan.hussain but my real name is Furqan Hussain
The users must not be displayed more than once. Not allowed to use SED, AWK or make use of temp files in script
. The output should look similar to this.
Furqan Hussain
PID TTY TIME CMD
31799 pts/3 00:00:00 vim
31866 pts/3 00:00:00 vim
2495 pts/7 00:00:00 vim
8368 pts/0 00:00:00 vim
9544 pts/2 00:00:00 ps
Alistairr Rutherford
PID TTY TIME CMD
8368 pts/0 00:00:00 vim
9544 pts/2 00:00:00 ps
Write the output to a file called processes.
A friend gave me the following to me:
#!/bin/bash
who | cut -d" " -f1 > onlineusers
noUsers=$(wc -l < loggedon # loogedon file contains list of loggin names of logged on users
count=1
while [ $count -le $noUsers ]
do
user=$(head -$count loggedon | tail -1)
finger $user > onlineusers
grep $user onlineusers | cut -d":" -f3 > onlineusers2
head -1 onlineusers2 >> processes
ps -U $user >> processes
echo >> " "
echo >> " "
count=$((count+1))
done
The above script does the job, however I can not use it because it uses temporary files, highlighted in blue. does anyone know how to substitute the temp files with coding that does same operation? Is there another way to write this? CAN ANYONE HELP?

pidof
PIDOF(8) Linux System Administrator's Manual PIDOF(8) NAME
pidof -- find the process ID of a running program. SYNOPSIS
pidof [-s] [-c] [-n] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] program [program..] DESCRIPTION
Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts are located in /etc/rc?.d, where ? is the runlevel. If the system has a start-stop-daemon (8) program that should be used instead. OPTIONS
-s Single shot - this instructs the program to only return one pid. -c Only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be unable to check the current root directory of processes they do not own. -n Avoid stat(2) system function call on all binaries which are located on network based file systems like NFS. Instead of using this option the the variable PIDOF_NETFS may be set and exported. -x Scripts too - this causes the program to also return process id's of shells running the named scripts. -o omitpid Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof pro- gram, in other words the calling shell or shell script. EXIT STATUS
0 At least one program was found with the requested name. 1 No program was found with the requested name. NOTES
pidof is actually the same program as killall5; the program behaves according to the name under which it is called. When pidof is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is possible that it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs. Note that that the executable name of running processes is calculated with readlink(2), so symbolic links to executables will also match. SEE ALSO
