here is the screen shot of both the script and output i don't get it??

I created a bash script that greps each line in FILE_A over in FILE_B and writes the result of the grep to a new file.
This whole process is taking over 5+ hours.
I'm looking for suggestions on whether you see any way of improving the performance of my script.
I'm using grep -F -m 1 as the grep command.
I need a script that could take in a line from one file and match the line up with codes in the order file.
My first file, called names.txt ,contains:
>123456789
>987654321
>15946873
>157987513
The other file, called data,contains:
GB_00012.faa
GB_6789333.faa
GB_100098.faa
GB_1237700.faa
All the data files contain a line startin with ">" symbol, and contai

Hi I am trying to write a script which runs until the host is up. i got it figured out that it needs to be in loop till it return $? = 0.

Hey everyone, I have a very simple BASH shell script that simply checks what processes I have running on a few different nodes, which are preknown. Currently, my script spews out all the processes on all the nodes, but I'm really only interested in one process per node. The processes I am interested are the only .exe processes on the nodes.
I'm trying to run a node.js script at boot using crontab.
Here's the command
/usr/local/bin/forever -c /usr/local/bin/node start /var/www/html/lights.js >/var/log/lights 2>&1 &
At reboot, the cron log says that the command was executed, but the lights log shows this
/usr/bin/env: node: No such file or directory
Running the command works, just not when cron runs it.
