Yeah on multiple line code in my first reply will fail. However following appears to work in ksh:
Code:
sed '1s:\<falsemodule-option\>:\<falsemodule-option\>\<LdapLogin\>:'


EDIT: Checked this with example works only for line number specified Smilie .

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 AUTHORS
