General :: Parse Through File Using Array Variables

Apr 26, 2011

I need to parse through a file which contains timestamps of transactions. What I am trying to do is come up with a Max Transactions Per Second (TPS) value. I was thinking that creating an array variable would be the way to go, but I'm having problems determining even how to start.

General :: Variables In Text File - How To Get Values When Printing Out

Apr 13, 2010

I'm doing some bash-scripting and want to be able to print some text (just plain text) files into the new bash-scripts, created within a loop. Here's a short example of what I do:

# main bash script #
for ((j=0;j<=40;j+=1))
## Create another bash-script
echo "#!/bin/bash" >> bash_script_$j
... some stuff...
cat file1.txt >> bash_script_$j
... some more stuff...
where the text file (file1.txt) I want to print in the the new bash script looks something like:

# file1.txt #
...some stuff...
logsave log some_program($variable1)
mv output_$j folder_$j/
... some more stuff...

I.e, the text file contains variables such as "$j", "$variable1" etc that are undefined. Doing the above works for creating new bash scripts (bash_script_1 - bash_script_40) but the variables are not determined. I would like, if possible, to somehow print the text in file1.txt into the new bash-scripts with the variables determined, i.e:

# bash_script_1 #
...some stuff...
logsave log some_program(10)
mv output_1 folder_1/
... some more stuff...

The text files I read are quite extensive so I would really prefer not having to paste them into the FOR-loop directly.

General :: Parse A File And Print Each Line That Ends With Matching Pattern (if The Next Line Is Blank)

Aug 2, 2010

I've written a script to parse a file and print each line that ends with matching pattern, if the next line is blank. The pattern lines are the result of md5sum $i|sed 's/path///g' so that only md5 and filename appear. Here's what I'm using.

for fline in `sed -n '/.*.ext$/p' file1`
if [ "`sed -n -e '/'"$fline"'/ {n; p;}' file1`" == "" ]
echo ""$fline" has no info" >>file2

I have a file called outside_temp that has a single number, say, 63.2

I would like to make a variable in a BASH script have that value.

I know how to use the input redirection and reassignment of stdin using code...

Programming :: Working With System Call - Read Output And Parse Values

Dec 10, 2010

I have the following code:
#include <stdio.h>
#include <stdlib.h>
int main() {
system("ps -ef | grep myprocessname");
return 0; }

When I run this program it outputs the following list of running processes:

root 10341 10337 1 13:02 ? 00:00:00 myprocessname myvar1=value1 myvar2=value2

What I want to really do is instead of writing the output to screen I want to read the output and parse the various values value1, value2 etc. What is the best way to do this?

Programming :: BASH - Output Of Snmpget With Multiple OIDs Into Separate Variables

Jul 7, 2010

I have a problem with snmp answers being empty or having spaces.

What I already have:

#get all interface indexes (if you wonder - I'm working for a cable company and different cablemodems have different number and types of interfaces):

The problem is the physical address which is sometimes empty and the description which has spaces. So I'm doing 2 snmpgets which is slower than 1 snmpget (sometimes I have up to 18 interfaces).

I'm trying to explain it a bit simpler.

Interface 5 gives me back the following lines:

Ethernet CPE Interface

Now the first line should go into variable ifadm,
2nd line should go into variable ifoper,
3rd line should go into variable ifspeed,
4th line should go into variable iftype,
5th line (which is empty) should go into variable ifphys and finally
6th line (which has spaces) should go into variable ifdescr

OpenSUSE Install :: Yast Hangs At 99% Downloaded - Aria2c Can't Parse Progress Line [11.3] / Fix It?

Sep 6, 2010

I've just upgraded to 11.3, as a result, the suse-supplied video driver runs very slowly (screen-saver updates about 2 fps, to give you an idea) On 11.2, I had installed nvidia's native driver and things were just fine, so I tried to install the latest nvidia driver again, but I'm getting a hard hang with Yast -- at 99% downloaded, yast stops responding ("abort" doesn't respond, but an external "kill" signal works)

Finally getting the bright idea of checking the y2log file, I see the following code...

these three lines are repeated every second

I'm sure there are some fingers to be pointed [nvidia's ftp server is borked; aria2c is clueless, etc] but that does not help me - what do I need to do to convince this "aria2c" program that the file has, in fact, completely downloaded so that the installation process can continue?
