I'm trying to make a bash script that if a null value is returned then to output the value 0.
I would like a script to search the 'top' tree and return the CPU value of a process, however if the process is not running for it to return 0 or another identifier.
Any help appreciated.

When the user opened the csv, I wanted it so autofilter was already turned on in columns A1 and B1 (and potentially C1,... (1 Reply)

mv "name" "name\0"
with the \0 a real NULL.
Against all my efforts, I have not been... (2 Replies)

xsil2graphics
XSIL2GRAPHICS(1) User Contributed Perl Documentation XSIL2GRAPHICS(1)NAME
xsil2graphics - generate scripts to load xsil output data files
SYNOPSIS
xsil2graphics [options] <xsil_file>
DESCRIPTION
Utility program bundled with xmds, used to generate scripts that load simulation output data into either matlab (http://www.mathworks.com)
or scilab (http://www.scilab.org), which are then used to manipulate the results further if necessary and then to present the results
graphically.
Matlab
To generate a matlab m-file, from the xsil file data_file.xsil use the command:
bash$ xsil2graphics data_file.xsil
or
bash$ xsil2graphics --matlab data_file.xsil
Then at the matlab command prompt:
>> data_file
Scilab
To generate a scilab script file, from the xsil file data_file.xsil use the command:
bash$ xsil2graphics --scilab data_file.xsil
Then at the scilab command prompt:
--> exec('data_file.sci')
OPTIONS -m, --matlab generate matlab m-file script to load data from the xsil data file (the default option)
-s, -scilab generate scilab script file to load data from the xsil data file
-o, --outfile <out_file> specify an alternative output script filename to the default which is the input xsil filename with the .xsil
extension changed to either .m for the matlab m-file or .sci for the scilab script file
EXAMPLES
bash$ xsil2graphics nlse.xsil
Generates the output nlse.m to load the data into matlab
bash$ xsil2graphics -m nlse.xsil
Also generates the output nlse.m but explicitly sets matlab to be the output format
bash$ xsil2graphics --scilab nlse.xsil
Generates the output nlse.sci to load the data into scilab
bash$ xsil2graphics --outfile nlse_new.m nlse.xsil
Generates the output nlse_new.m to load the data into matlab
