RudiC,

I get error with that sed command. once we fix this command, i need to put it in a for loop for processing list of all my input files and see if i do not get my original issue here too.

and other part is, my input file may contain other ~variables~ which are not part of a.txt. so those should be remain same.


Code:
$more b.txt
line1
line2
~variableA~
line4

$more a.txt
variableA=/proj/apps/sun
variableB=/tmp

$sed 's:^:s#~:; s:=:~#:; s:$:#:; ' b.txt | sed -f- a.txt
Cannot open pattern-file: -

OS version:
SunOS ahs2518 5.10 Generic_150400-27 sun4v sparc sun4v

Thanks

It looks like if matching and deleting the last line confuses 'sed' so it does not recognize '$' address.

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a filename containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
