Thanks drysdalk. Had some errors when converting the obtained broadcast address. Just replaced step 1 and 2 with:
ping -i eth0 255.255.255.255 -b

Problem solved. ;)

Hi,
I want to build a list of the devices that are connected to my network and refresh that list every 10th minute (using an RPi with Raspbian). The host names are obtained by using Bonjour which is...

I'm monitoring a WLAN network to keep track of new SSIDs popping up. The SSIDs are stored along with the AP MAC address and a few other parameters in a CSV file. A typical line could look like this:...

Hi Don,
Seems you have a valid point. I removed the "&" and it still works fine. Thanks.

Thanks to your comments above, I managed to solve the problem. I made two changes:

1. In crontab, I added an '&':
0-59/5 * * * * /usr/myFolder/start.sh &

2. I added the working directory for...

Thanks Rudi. I will try to fix it and post the "solution" here once done. It doesn't have to be exact, it can be a bit late but not drift.

Thanks for all replies. I tried calling for a more simple file (echo "hello") and it works fine, so it seems that the problem is related to that I try to run scripts that are calling for other...

Back to this one again. Tried to automate a script called getStats.sh that looks like this:

#!/bin/bash
./startMeasuring.sh
./collectStats.sh

I go to crontab -e and add this line:
0-59/5 * *...

Ok, tested and that was EXACTLY what I wanted to achieve. Thanks a lot Corona688! :D

Thanks for suggestions. I need this to happen at exactly 5 min intervals as I have other databases with values also from each 5 min and I want to be able to print data from different tables in the...

Hi,
I have a bash script that generates CSV (.txt) files at fairly regular time intervals. I'm currently time stamping each batch of measurements at the time I write the rows into a MySQL database....

Thanks a lot for all suggestions, very useful information. I got the original file to work by changing the loop to:

for(i in colors)
printf("%-17s %10d %14d\n", colors[i],...

Hi,
I have a text file with some thousands of rows of the following kind (this will be referred to as the inputFileWithColorsAndNumbers.txt):

Thanks a lot RudiC. #5 was just what I was looking for. :-)

Thanks RudiC! Just get a minor error (also added one missing dash in your command):
$ awk 'FNR==NR{a[$1]=$2 FS $3 FS $4;next}{ print $0, a[$1]?a[$1]:"- - -"; delete a[$1]} END {for (i in a) print i,...

Using Linux (bash), I have two files which contain information about berries. Example:

file1.txt:
Blueberry blue 14
Raspberry red 12
Blackberry dark 4

file2.txt
Blackberry sour 4 3...

Excellent. Thanks. Final question then: If I do all of this in a bash script and want to replace file1.txt with a command, for example:
date "+%y%m%d %T"

which right now gives the following...

Thanks a lot MadeInGermany, that did the trick!

Don, for the record here are my two files and the desired output (which I get with #5):

file1.txt
ABC

file.txt
123 456 789
321 654 987
222...

Thanks a lot. This works excellent when file.txt only has one column. Trying to add more columns there like this:

file.txt:
123 456 789
321 654 987
222 444 555


When I run your command...

I have two files with the following content:

file1.txt looks like this (it always only have one single row):

ABC

file.txt looks like this (may have tons of rows):
123
456
789

I want to...

I have a small Linux device that measures some IP stats from one network and then generates some stats files (csv format) based on the input at certain times. I want those stats files to be...

Hi Don,
Sounds fantastic, thanks! I removed the brackets and as you said it now runs and it's stuck in an infintie loop as you say. I added an additional counter to stop the loop and I get some sort...
