I'd like control-u to erase the whole line, instead of only erasing backwards from the current point. I tried
bind -r "C-u"
bind -r C-u
bind -r ^U
to erase the current binding for control-u, but after running any / all of the above, bind -p still tells me
"C-u": unix-line-discard
bind "C-u":kill-whole-line doesn't work either. How can I change the binding of control-u to kill-whole-line?
I was giving the found the following shell script. I was told it was suppose to ensure only that only one script of Test.sh can run..
However, I get it looks like it has a error when i run it... As i get Test.sh: line 9: kill: (20831) - No such process
what is going on in this script can someone explain it to me... I thought it suppose to work like a singleton for my script creating a file .run-test-sdolan. However, i don't see how or where .run-test-sdolan is create?

The for statement is a placeholder as I have same file to backup out of several directories. using "bash -x scriptname" -OR- inserting echos, I can see I've constructed the strings properly.

As you can see, I attempted to build in a protective measure to prevent duplicate entries using "if grep -Fxq "$FN $LN" /home/andrea/namelist.txt", FN and LN being first name and last name as you can see in the first read operation. However, this fails to actually work. Demonstrations:

It saves the details to the file rather than displaying the error message, or in other words, it doesnt check the file properly.
Using Lucid and most things seem to be going OK but I can't get the computer to take the line-in signal.
It's an AsRock M3A785GMH/128M mainboard (ALC888 Audio) and I'm on Lucid 64-bit.
I've checked the jack's in the right socket, that the input is elected in both the normal ALSA volume control and pulse, and that the volume controls are turned up.
I know also that there is a signal going into the line-in lead!
I am trying to read the names of hosts from a file and do a ssh to see if processes are all running or not.
Here is the outer loop that is causing problem:
hosts.lst is a text file that has the host names in each line.
The problem is that the loop just breaks after the first run. Somehow while read line becomes invalid when the body of the loop does the ssh and returns.
How do I kill a python application from the command line? For an example I have 2 applications running. The first is bleachbit and the second is furiusisomount. They are both python applications so they both come up as python under process name. I could kill them by ID number but if there was another way to do it so that it could be automated in a bash script.

bash 3.1.17(2) I'm trying do write a shell script which must operate on each line of an ASCII text file.

I'm trying to make another file annotation script a little speedier than it has been by the up-until-now proven method of checking the last four characters in a filename before the "dot" (eg .jpg, .psd) against a list of known IPTC categories and Exiv2 command files. It occurred to me that if one script generated a list of files in directory foo, and the same or another script sorted that list by that four-letter tag,then that list could be used(instead of a for/do/done loop on the real files in the folder) by the command-file-matching script to "vomit out" which annotator file would go with file nastynewfile.jpg, f'r'instance. The script I had been using for this task looks like this:
Code:
while read 'line';
do
sp=$(echo $line)
vc=$(echo $sp | cut -d"," -f1)
cv=$(echo $sp | cut -d"," -f2)

Where I seem to be stuck is with how to sort the lines in templist, which may be any number of different lengths, from back to front. sort -k looked promising, except it seems only to work the other way round. I thought of invoking a
Code:
q=$(expr length $line); echo $q
n=$[q-8]; echo $n
kind of thing, but that presented the problems of how to sort by those, how to tell sort where to find them (grep?) and how to "stitch them back in" to the original list, which is what I want to sort in the first place.
I'm trying to get multiple numeric valued version information into a variable, all on the same line. I want for example $VERSION=3.1.0.01.002. I'm trying to pull seperate values from the file named version.properties, wherein the file contains;
patch.rel.num=0
sqa.num=01
major.rel.num=3
build.num=002
minor.rel.num=1
So I have the following script:
#!/bin/bash
BUILDVERFILE="version.properties"
PATCH=`grep "patch.rel.num" ${BUILDVERFILE} | awk {'print $1'}`
SQA=`grep "sqa.num" ${BUILDVERFILE} | awk {'print $1'}`
MAJOR=`grep "major.rel.num" ${BUILDVERFILE} | awk {'print $1'}`
BUILD=`grep "build.num" ${BUILDVERFILE} | awk {'print $1'}`
MINOR=`grep "minor.rel.num" ${BUILDVERFILE} | awk {'print $1'}`
P=`echo $PATCH | tr -d .=[:alpha:]`
S=`echo $SQA | tr -d .=[:alpha:]`
MA=`echo $MAJOR | tr -d .=[:alpha:]`
B=`echo $BUILD | tr -d .=[:alpha:]`
MI=`echo $MINOR | tr -d .=[:alpha:]`
VERSION=$MA.$MI.$P.$S.$B
echo $VERSION #
I end up with the value of .002 ?? Seems like it's only getting the last portion because if I run the script thru "bash -x" I get:
...

.0
.01
.002

+ echo $'3

I would like to know how to troubleshoot, and fix this problem if possible (even a workaround would be great).
I have installed RHEL5, solved the problems around it and started to set up the GRUB. I have set the menu.lst with simple
rootnoverify (hd1,0)
mkeactive
chainloader +1
and tried to boot the Win7 on that partition. NO LOADER came up and since that moment
Grub is only in "Minimal BASH-like line editing" mode. I have tried all of I have googled, nothing have worked. There is a problem with even finding /boot/grub/stage2, or anything else, grub won't let me mount any partition. When I try to find any file, it says file not found. It is important to say that all I did to cause this was change in menu.lst
rootnoverify (hd1,1) to rootnoverify (hd1,0)m nothing else! There is no logic in this....

View 3 Replies View RelatedI am attempting to write a very basic script that monitors a server's load and automatically emails an administrator upon the load reaching a certain threshold...
1.) `uptime | awk -F ' ' {'print $10'} | cut -d ',' -f1 | awk -F '.' {'print $1'}` -- the output from this command results in a decimal figure, so when that value is parsed and placed in an if statement, the value is not seen as a number. load-monitor.sh: line 9: [: 4.96: integer expression expected/How can I allow a number like "4.56" to be seen as an actual number within the if statement and be compared to 4, for instance?
2.) I am running a cPanel server on CentOS 5.4 -- when I run mail -s "SUBJECT" $EMAILADDRESS the command just hangs, and stracing the process shows it stuck on a read syscall.
3.) If I wanted to write this script in PHP, I have one primary confusion -- how can I mimic the functionality of obtaining the output from uptime via awk, etc. so that I can determine what the server load is at a given time? Which PHP function(s) would assist in that regard?
I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail.
The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?
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)?

I set up Samba using command line terminal, and my network does not work. I have Samba username and keyring passwords all set, then I go to gui system-config-samba, and my samba user profile password is incorrect. In the past, I have used a 10 letter password, however, every time I boot the computer, I have to go back in and re-enter the password.I wonder if samba is truncating the password because it only accepts an 8 character password? I have deleted the user, and added a new username, and it is still doing it.
If I go into the gui and re-enter the password, usually I can get the network back up with my windows machine. All of the parameters are correct, I use the network to transfer files from my Windows to my Fedora drive all of the time when it works.
