NAME
ch_rc - change system configuration file
SYNOPSIS
root] {parameter|parameter=value}...] [file...]
DESCRIPTION
manages the addition, modification, removal, and retrieval of information stored in files having the format of those in the directory.
Parameter names are treated as strings. Thus, has no special meaning to in relation to other parameters named
Options
file Specify the file(s) to be used as the configuration database. If no file is specified, the set of files used by defaults
to and all files in the directory.
Modification and deletion of configuration parameters occurs in the file where the parameter is found.
Add or modify a parameter definition. For each parameter specified
on the command line, if the parameter is found in the specified (or default) files, it is modified to reflect the speci-
fied value. If the parameter is not found, it is added to the specified file(s).
If a new parameter is being defined, one or more files must be specified on the command line; the specified files are
those in which the parameter will be defined.
Remove a parameter definition. For each parameter name specified
on the command line, remove any occurrence of that parameter from the specified file(s).
List configuration values. For each parameter specified on the
command line, output every definition of the parameter from the specified file(s). Output consists of only the values,
one per line.
Specify a parameter name or name/value pair. If a name and value
is expected, but only a name is specified, the value will be set to the empty string. For example, specifying or will
result in and respectively.
Due to shell quoting rules, if you need a quoted parameter value, you must protect the quotes from the shell. For exam-
ple,
yields:
which is an error, whereas,
yields:
Verbose. When used with the
option, the option causes a verbose listing to be output. This listing includes a filename followed by the entire line
containing the specified parameter for each occurrance of the parameter.
The option is used to list all occurances of array parameters matching the parameters specified on the command line.
For example,
may emit the following output:
Normally, the files specified on the command line are used as specified.
By specifying a root directory with the option, all files (including the default files if none are specified) will be
interpreted relative to root.
For example, if root is specified as and is specified on the command line, it will be interpreted as
RETURN VALUE
exits with one of the following values:
0 add/delete/list successful
1 command line syntax/usage error
2 can not access one or more of the listed (or default) files
3 can not open/create/write file
4 memory error
5 no files specified on command line for add option
EXAMPLES
Files in the directory have the following format:
WARNINGS
does not interpret configuration files; it only does pattern matching. As a result, if comments appear on lines containing parameter defi-
nitions, the comments will also appear in output when using the option.
cannot parse multiple parameter definitions which occur on the same line of a file.
