crudini - A utility for manipulating ini files Usage: crudini --set [OPTION]... config_file section [param] [value] or: crudini --get [OPTION]... config_file [section] [param] or: crudini --del [OPTION]... config_file section [param] [list value] or: crudini --merge [OPTION]... config_file [section] Options: --existing[=WHAT] For --set, --del and --merge, fail if item is missing, where WHAT is 'file', 'section', or 'param', or if not specified; all specified items. --format=FMT For --get, select the output FMT. Formats are sh,ini,lines --inplace Lock and write files in place. This is not atomic but has less restrictions than the default replacement method. --list For --set and --del, update a list (set) of values --list-sep=STR Delimit list values with "STR" instead of " ," --output=FILE Write output to FILE instead. '-' means stdout --verbose Indicate on stderr if changes were made --help Write this help to stdout --version Write version to stdout Examples: # Add/Update a var crudini --set config_file section parameter value # Update an existing var crudini --set --existing config_file section parameter value # Delete a var crudini --del config_file section parameter # Delete a section crudini --del config_file section # output a value crudini --get config_file section parameter # output a global value not in a section crudini --get config_file '' parameter # output a section crudini --get config_file section # output a section, parseable by shell eval $(crudini --get --format=sh config_file section) # update an ini file from shell variable(s) echo name="$name" | crudini --merge config_file section # merge an ini file from another ini crudini --merge config_file < another.ini # compare two ini files using standard UNIX text processing diff <(crudini --get --format=lines file1.ini|sort) \ <(crudini --get --format=lines file2.ini|sort)
