where parChk="//---ee-"

How can i print the variable value from sed command ?
And is it possible to replace a specified line without ruining other lines ?

I am trying to write a script that replaces the

//---- (dashes upto < 79 coloumns) pattern to //---- (dashes upto 79 which is standard) inside any *.cpp file.


Kindly help &
Thanks in advance.

Try changing the delimiter from / to +.
Code:
echo "//-----" | sed "s+//---*+$parChk+g"

If you want to change a particular line or a range of lines

Code:
echo "//-----" | sed "L1,L2s+//---*+$parChk+g"

where L1 is the first line number of the range-of-lines you want to change. L2 is the ending line number of the range-of-lines you want to change. If you want only a particular line to be changed, then L1 and L2 will remain the same.

NAME
nwbpset - Create a bindery property or set its value SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with As another example, look at the following command line: nwbpvalues -t 1 -o supervisor -p user_defaults -c | sed '2s/.*/ME/'| sed '3s/.*/LOGIN_CONTROL/'| nwbpset With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object 'me'. nwbpvalues -t 1 -o me -p login_control -c | sed '9s/.*/ff/'| nwbpset This command disables the user object me. Feel free to contribute other examples! nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the user name to use for login. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset prompts for a password. -n -n should be given if no password is required for the login. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. AUTHORS
