Hi, I've written a utility to maintain text files that follow the "VARIABLE=value" format.
This file format is used by Redhat amongst others but its applicable to any small configuration file or very simple flat file database. It also is very useful for embedded systems for storing application configuration information and simple cgi scripting (this is what I wrote it for). Its also a good way to get stuff in and out of bash as in MYIP=`readwriteconfig -r /etc/sysconfig/networking/ifcfg-eth0` and readwriteconfig -w /etc/sysconfig/networking/ifcfg-eth0 IPADDR=$MYIP Anyway .. I called it readwriteconfig, its partly documented - if anyone wants it I will finish the documentation. Its coded in plain C. This is a simplified overview. The read mode is similar to grep, but exists the code once the string has been found. The write mode could be done with other sets of utils, but having a utility makes it more accessible. "readwriteconfig -r <filename> VARIABLENAME" Returns variable value or a fail code' "readwriteconfig -rs <filename> VARIABLENAME" Same, but fails silently "readwriteconfig -w <filename> VARIABLE=value" Update the line in the file replacing the OLD value if found, appending it if not. If it fits here let me know and I will put the source up somewhere.
