Programming :: How To Parse And Modify Keywords Using Shell Script?

Apr 14, 2011

There is a file with that format of each models' information.I don't think that's good format, but I cannot change that format. I needed to modify the model name, 'model = xxx' as 'model = abc'.And I don't know how to parse and modify 'model = iii' and 'model = ddd'.The only clue to parse 'model = ddd' is the second 'model = ' after the second 'system information'. But how to parse the second keyword?Is it possible with 'sed'?I sometimes have to modify the information of the file.using shell script if possible.Python is ok. (Shell script is better for me.)

Programming :: Parse And Modify File Without Creating A Copy?

Nov 4, 2010

I don't think this is a "perl one-liner" of find and replace. I'm trying to auto-fill some information in a listing of files. The simplest example is that in the files the following exists:

I would want the script to find this and populate it with something like -- Date : 20101004-1758

I have a few more similar fields to autofill, and I'd like to do this from within a larger perl script I'm developing to process these files. So, how I perform in-place file modification from within a perl script?

Programming :: Modify Output Of Shell Script

Dec 3, 2010

I'm running RHEL5.5 and nagios 3.2.0. The real question deals with how to change the printed output so nagios will work with it.I have made a script that will calculate network throughput on interfaces. The script is going through and finding all interfaces (eth, bond, lan) and doing the math to calculate throughput.The output is mainly for nagios to report and trend the values. As nagios wants to see nothing but perf data after the '|' character, I somehow need to have only one '|' character for all of the output.

Programming :: Bash : Searching For Info And Changing The Color Of Keywords In The Results?

May 5, 2011

(bare with me as I am sort of new with scripting) I am trying to figure out how to run a script that does a basic chkconfig and to get only those services that are running, but changing the color of "on" to red in my output file. Here is what I am working with so far:

Quote:

#/bin/bash
RED=$(tput setaf 1)
BLK=$(tput setaf 0)

[code]....

*I had to substitute a "-" and <colon_symbol> for ":" in front of the on's, because the forum thought they were smiley faces (i.e. n) how to make the "on" to be red while the rest of everything remains in black text. I have been trying to read up on sed and awk, but it is still pretty much a mystery to me right now. There will be other things in the output file that I wouldn't want a rogue "on" to be in red, so just the instances of "on" in that one chkconfig return.

Debian Multimedia :: Conky Execp / Execpi To Parse Output Of Scroll Variable Generated From Shell Or PHP Scripts

Sep 11, 2015

I am having a hard time getting conky execp/execpi to correctly parse output of the scroll variable generated from shell or PHP scripts.

Code: Select allDebian 8.0
Xfce 4.10
Conky 1.9.0-6

This is a simplified minimal conky configuration file used to show the same problem:

Code: Select allalignment bottom_middle
background no
border_width 1
default_color white
default_outline_color white
default_shade_color white
double_buffer yes

[Code] ....

Here is the output I'm getting:

Code: Select all          ABC       /*doesn't scroll, UNEXPECTED, shows 10 spaces before ABC*/
          ABC       --||--
abcdefghijklmnopABC /*doesn't scroll, WORKS AS EXPECTED as scroll length is 25 which is longer than text "abcdefghijklmnop" */
abcdefghijklmnopABC --||--
abcdefghijklmnopABC /*WORKS, everything before ABC scrolls 5 characters at a time*/

Programming :: Perl: Find Variable Text Between Keywords And Replace W/ "term_<variable_text>_term"?

Jul 12, 2010

I am trying to write a Perl script that can open a file, find text that appears between two identifying strings (for now, "start" and "end"), then modify that text by enclosing it between "term_" and "_term" . Since the identified strings vary, the replacement string becomes "term_$1_term". From looking at other threads in this forum I've been able to get as far as spitting out the modified terms using the following code:

open FILE, "start2.txt" || die ("Could not open file <br> $!");
$text = <FILE>;
while ($text=~ s/start (.*?) end//) {

[code]....

The problem is how to get "term_$1_term" into the file in the same while loop, which I'm guessing would be some of variant of "$text=~ s/$1/$term/;" (which doesn't work as it stands).

General :: Modify A File Like /etc/gdm/custom.conf From The Shell Or A Script?

Jun 22, 2010

I want to modify a file like /etc/gdm/custom.conf from the shell or a script.

# GDM configuration storage
[xdmcp]
[debug]
[daemon]
AutomaticLoginEnable=true;
AutomaticLogin=username;

But the idea is that I can add a line to a section and it check if the section is defined, (add the definition if not), the property is defined, let it undefine (erase the line), (and delete the section header if there is no property defined), etc...

I didn't find anything except gconftool-2 but it do not explain how to modify other files. (there is a shema file there).

there isn't a program/script to achieve this, but can easyly be made for every config file, If someone do something like that, with a little database of which markup use each file, it could become really popular.

Programming :: Parse Text For Host List?

Feb 22, 2011

To run a parallel chemistry program, I need to build the host list. The cluster already has SGE(grid engine) installed and it generates a host list file with the following contents:

Programming :: Bash - Parse Apache Log For Requests Per CIDR / 24

Feb 6, 2011

I'm trying to figure out how I can get a request count per CIDR/24 from an apache log in combined format - e.g.:
Code:
24.147.44.122 - frank [10/Oct/2011:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326 "[URL] "Mozilla/4.08 [en] (Win98; I ;Nav)"

I'm stuck using BASH for this and I generally write everything in Python, or even Perl if necessary so BASH isn't the most comfortable for me. I've got enough to extract the IPs and get a count I just need a slick way to come up with a sum on a per CIDR basis.
