i was wondering if anyone could give some advice on how to write a bash script that would print processes using more than x mb or x% of the CPU?

Where the numbers are the number of processes being run by the user (the name right next to it).if I input the command egrep myFile into the terminal, it should look for every line with the letter x in myFile, right?

I'm running my website on a linux server. I'm using a mac. Apparently, mac mail has a bug where it creates too many imap processes.
Since I'm on a shared server with a 25 process limit, with 3 email accts x 4+ processes each = a lot of problems!
I'm trying to write a cron job to delete imap processes every minute.
I've tried two things
1) following this blog's advice [URL]
Code:
killall imap
i realised it was imapd not imap, but i tried another method anyway
2) create a kill-imap.sh file in my server folder.
Code:
#!/bin/bash
/usr/bin/killall imapd
then executing the file from the cron command /kill-imap.sh
both these cases, it didn't seem to work!
I would get a daemon emai reply with
imapd: no process killed
just to give more info, the existing imap processes look like this
/usr/lib/courier-imap/bin/imapd /home/sitename/mail/sitename.com/emailusername
honestly, I'm not too experienced in this, and i've searched the net without luck. can anyone advise what i'm supposed to do to kill these imap processes every 5 min via cron job?

The application I am using writes a report file (ascii), but I am not able to print it, because from inside the application I have no access to the shell and so cannot invoke any printing command (lpr, lp, ...). Is there a tool/daemon which waits for a file in a given directory, takes it, and sends it to a printer?
View 6 Replies View Relatedi am using putty to connect to the linux server and i am using nano as my text editor to write a bash script.
this is my script:
echo "Please enter your Username"
read userName
userName= grep $USER /etc/passwd | cut -d: -f5
echo "Welcome " $userName | cat >> output.txt
the problem i have is that when i enter my username, the output (my real name) does not display in the output.txt. instead it displays in putty. so when i run my script in putty it shows the message to enter username and after i enter my username my real name appears below it. i want it to show in the output.txt

I am trying to write a bash script that sources another bash script. Essentially, I need a few lines to check to see if a certain variable is set. If not, I set it manually, and then source a scripts with that variable in the path. I wrote a test script to try it, but for some reason the last line does not work. Here is what I wrote:
#!/bin/sh
source ~setupdir/setup.shrc #just a test, this line works
echo ${#SETUP} # prints 0 if setup is not set, which it isn't
if [ ${#SETUP} -eq 0 ]
then
SETUP="~setupdir"
fi
echo $SETUP # prints ~setupdir

This pretend to be a script for rename a lot of files automatically. So I put the list of files in an array named @lista. But, as you can see, at the end of the command I use a sed filter to print out a backslash for those files that have spaces in their names, so the path for those files could be rightly interpreted.
But there's no way I could print a backslash. It works well when I use the Perl's sed substitution s///, but I need every path in the array to be fixed.
I'd like to add that the bash command works perfectly well alone. I mean outside the Perl script.
This is de command line with the sed filter:

And this is what it brings:

I'm trying to avoid kill -9 for the reasons described in the Useless Use of Kill -9 form letter. Is this function sufficient, or do I need to kill the kill processes after a timeout or take care of other subtleties?
soft_kill()
{
# Try to avoid forcing a kill
# @param $1: PID
kill $1 || kill -INT $1 || kill -HUP $1 ||
(echo "Could not kill $1" >&2; kill -KILL $1)
}
As an aside, what's a better name for this function? The current name reminds me of "Killing Me Softly", and manslaughter sounds a bit severe. Maybe spoon_kill (Google it)?

View 4 Replies View RelatedI've been looking for how to set this up in bash with no luck so far. I can change what file the history log is written to, and how much history is saved. But it only writes the saved part when bash exits. Instead, I'd like to have bash write that file continuously as each command is entered (and maybe also do an fsync(2) to flush it to disk). That way I can see the command I crashed the box with Anyone know the magical incantation for that?
But there appears to be nothing that I can find there, in the man page, or other searches, that suggest it even can do continuous.
