Ubuntu :: Sort The Output To A Text File So That It Prints To The Text File At 1 Process Per Line?

Feb 6, 2011

im trying to output a list of running processes via a shell script. At the moment i got this which outputs the processes to a text file called out.

echo $(ps aux) >>out

The problem is though, the processes are all just one big block of text which makes it hard to read. Does anyone know how to sort the output to a text file so that it prints to the text file at 1 process per line? I know its probably simple but im very new to linux.

General :: Read Data From Text File And Output Into A Table?

Apr 12, 2010

I'm having a slight dilemma on reading data from a text file and outputting it into a table then displaying it. Basically I'm writing a shell script that takes information from text files then outputs the data into a table with 4 headings.he extracting of the data is fine, but creating a table i'm having problems with.

General :: Write A Bash Script That Will Read The Word From The Text File?

Jun 10, 2011

I have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)

Code:
#!/bin/sh
for f in value.txt
do
echo $f
done

so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?

Programming :: Delete Line Of Text From Text File Via Shell?

Jan 13, 2010

I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

Fedora :: Write A Shell Script That Will Look At Each File?

Jul 23, 2010

I have a number of text files throughout my /home/pjs/Documents directory tree that have execute permissions set. Almost all of my file names have spaces in them. I am trying to write a shell script that will look at each file in my Documents directory, find the ones that have execute permissions set, and run the command chmod 644. Of course, I don't want the command run on the directories.

The following script *doesn't work*, but might serve to illustrate what I am trying to do:

#!/bin/bash
for x in "$(ls -R)" do
if [ -f "$x" ] && [ -x $x ]; then
chmod 644 "$x"
fi
done

I want each file and directory name to be placed, one by one, in the variable $x, and then tested with the "if" conditionals.

The first problem seems to be that, although the command "ls -R" does produce a complete list of the files and directories I need, they are not placed, one by one, in the variable x like I want them to be.

Also, I think I should use the shift command so that the option -R doesn't get included as one of the values of the variable $x, but I can't figure out where to put it.

Programming :: Write A Shell Script Which Edits A Config File ?

Mar 1, 2011

Write some simple script?

Heres what Im trying to do:

-Qjackctl has a config file which is modified each time QjackCtl is shut down. This means that whatever preset is in use when QjackCtl closes is written into the QjackCtl config file as the DEFAULT PRESET, for the next time QjackCtl starts (or at least this is how I understand it).

-I want to edit a specific line in the QjackCtl.config file, which specifies the DEFAULT PRESET. Obviously its easy to do manually, but I want to do it using a shell script which runs automatically on StartUp so that QjackCtl starts every time with the same DEFAULT PRESET, NOT the last one used.

-Unfortunately Im not at my Linux system right now (which is KXStudio/Kubuntu), but I believe the QjackCtl.config line looks something like this: DEF_PRESET=alsa (where alsa is the name of the preset)

PRESET1=alsa
PRESET2=firewire

I want a shell script which changes the line DEF_PRESET=alsa to DEF_PRESET=alsa, even when it may currently exist as DEF_PRESET=firewire due to occasions when firewire was the active preset when Qjackctl was last closed. I notice that the application in KDE that enables the user to set which applications open automatically on StartUp also allows the user to select shell scripts.

Ive done some research, as a beginner, and Im led to believe I might need to use AWK and/or CHMOD. I could have a go at writing a shell script but Im always wary about experimenting with StartUp scripts/operations because obviously if I get it wrong and make my system unusable, then because its going to run first thing on each boot, Id have great difficulty disabling it.
