Top Forums Shell Programming and Scripting How to walk through a config file with /bin/sh Post 302347744 by zaxxon on Wednesday 26th of August 2009 10:01:05 AM

So if I understood it correct, you have problems with the substitution in the file.
If you have no problem to set up the while/read loop to get the wanted input, you can use the values stored in variables with for example sed to exchange the current values in the config file with the new ones.
Here a general example how substitute patterns:

Code:
# you got VAR filled with a value by your former read/while loop of course
sed "s/oldvalue/${VAR}/g"

Do this for several of your patterns and write it to a tmp file and maybe mv it over the original. Could take a backup before doing it.

NAME
git-var - Show a Git logical variable SYNOPSIS
git var ( -l | <variable> ) DESCRIPTION
Prints a Git logical variable. OPTIONS
-l Cause the logical variables to be listed. In addition, all the variables of the Git configuration file .git/config are listed as well. (However, the configuration variables listing functionality is deprecated in favor of git config -l.) EXAMPLE
$ git var GIT_AUTHOR_IDENT Eric W. Biederman <ebiederm@lnxi.com> 1121223278 -0600 VARIABLES
GIT_AUTHOR_IDENT The author of a piece of code. GIT_COMMITTER_IDENT The person who put a piece of code into Git. GIT_EDITOR Text editor for use by Git commands. The value is meant to be interpreted by the shell when it is used. Examples: ~/bin/vi, $SOME_ENVIRONMENT_VARIABLE, "C:Program FilesVimgvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable, then core.editor configuration, then $VISUAL, then $EDITOR, and then the default chosen at compile time, which is usually vi. GIT_PAGER Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually less). SEE ALSO
