How to get content of a variable into text file (sed)?
Hello,

Im working on this problem for 3 days now and i just cant get it to work.. I tried with alot of different sed methods but didnt find any solution. Its proberly verry simple but i just started bash scripting for a month or so..

i have a file called: file.nfo and file.txt
the content of file.nfo is
Code:
test23423
test 234
test3443
whole lot of text

the content of file.txt is
Code:
[nfo]nfotxt[/nfo]

I want to replace nfotxt with the content of the file.nfo
i do that with:
Code:
txtfile=file.txt
nfo=file.nfo
nfotext="$(cat "$nfo")"

then i use sed to search and replace like:
Code:
sed -e "s/nfotxt/$nfotext/g" $txtfile

i also did an escape \ or qoute "$nfotext"

The problem i have is that it doesnt replace the nfotxt with the content of the file.nfo and that it wil replace it with $nfotext rather then the content.. Hope someone can enlighten me or point me in the right direction..

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

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
       'nwbpvalues -c'. See util/nwbpsecurity for an example.

       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.
