Like the topic says, does anyone know if it is possible to check to see when an FTP only user has logged in? Because the shell is /bin/false and they are only using FTP to access the system doing a "finger" or "last" it says they have never logged in.
Is there a way to see when ftp users log in... (1 Reply)
Hi,
There is a file having a list of running PIDs and another file having a list of registered PIDs. How can we check if the number of running PIDs are less or more than the registered PIDs, comparing the total no. in each and also each value.
Request you to pls give your inputs.
Thanks a... (2 Replies)
Hello,
I am trying to write a script that turns off the screensaver for a certain period of time, then come back on. I have had it up and running for a while, but then I decided to refactor it a bit for my family members that are less computer savvy.
I am starting a subshell for the "meat" of... (4 Replies)
Hey,
So I'm new to shell scripting, and I'm trying to write one for my lab that will keep down the work load by deleting processes that are left over from previous sessions.
Basically I want it to do three things.
1) Check the processes running
2) See if that person is logged on.
3) if... (2 Replies)
I am trying to determine the root cause of a java process that dies trying to startup during it's cron job.
I did go ahead and change the time that it starts up in the cron file and now it starts successfully.
However is there a way to determine what PID a process was attempting to get when... (5 Replies)
Hi there !!!
I am writing a script to kill the pids on different linux boxes :cool:
the output of my command gives the pids running on that box, but how can I kill all the pids without looping? :confused:
Code:

Good afternoon
I need to KILL a process in a single command sentence, for example:
kill -9 `ps -aef | grep 'CAL255.4ge' | grep -v grep | awk '{print $2}'`
That sentence Kills the process ID corresponding to the program CAL255.4ge.
However it is possible that the same program... (6 Replies)
im looking for a portable way to get the PID of the script that is running, and to get every other PIDs that are spawned from it.
and by ever other PIDs, i presume, that would be "child processes".
however, i want to shy away from using any command that is not available on every single unix... (1 Reply)
First of all, I'd like to congratulate this big family and all members for all the work you do!
I'm trying to do an script or sentence which kills an specific printers PIDs: all printers PIDs older than 72h running in the server.
Steps:
1.- List all printers PID sorting by date:

sleep
SLEEP(1) BSD General Commands Manual SLEEP(1)NAME
sleep -- suspend execution for an interval of time
SYNOPSIS
sleep seconds
DESCRIPTION
The sleep command suspends execution for a minimum of seconds.
If the sleep command receives a signal, it takes the standard action. When the SIGINFO signal is received, the estimate of the amount of
seconds left to sleep is printed on the standard output.
IMPLEMENTATION NOTES
The SIGALRM signal is not handled specially by this implementation.
The sleep command allows and honors a non-integer number of seconds to sleep in any form acceptable by strtod(3). This is a non-portable
extension, and its use will nearly guarantee that a shell script will not execute properly on another system.
EXIT STATUS
The sleep utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
To schedule the execution of a command for x number seconds later (with csh(1)):
(sleep 1800; sh command_file >& errors)&
This incantation would wait a half hour before running the script command_file. (See the at(1) utility.)
To reiteratively run a command (with the csh(1)):
while (1)
if (! -r zzz.rawdata) then
sleep 300
else
foreach i (`ls *.rawdata`)
sleep 70
awk -f collapse_data $i >> results
end
break
endif
end
The scenario for a script such as this might be: a program currently running is taking longer than expected to process a series of files, and
it would be nice to have another program start processing the files created by the first program as soon as it is finished (when zzz.rawdata
is created). The script checks every five minutes for the file zzz.rawdata, when the file is found, then another portion processing is done
courteously by sleeping for 70 seconds in between each awk job.
SEE ALSO nanosleep(2), sleep(3)STANDARDS
The sleep command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
HISTORY
A sleep command appeared in Version 4 AT&T UNIX.
