gschem accepts several optional arguments on the command-line. You can get a list of them by running gschem -h. gschem also has a manpage (man gschem) which lists all of the command line options that it accepts.
| -q, --quiet | Quiet mode. Turn off all warnings/notes/messages. |
| -v, --verbose | Verbose mode. Output extra diagnostic information. |
| -h, --help | Print a help message. |
| -V, --version | Print gschem version information. |
| -L DIRECTORY | Prepend DIRECTORY to the list of directories to be searched for Scheme files. |
| -s FILE | Specify a Scheme script to be executed at startup. |
| -c EXPR | Specify a Scheme expression to be evaluated at startup. |
| -r, --config-file=FILE | Specify an additional configuration file to be read after all other configuration files have been processed. |
| -o, --output=FILE | Specify a filename for generating PostScript output. This command line argument is useful when running gschem from a shell script and with a Scheme script. The filename can be changed through the print dialog box. |
| -p | Automatically place the window. This may be useful if running gschem from the command line and generating output. |
| -- | Treat all remaining arguments as schematic or symbol filenames. Use this if you have a schematic or symbol filename which begins with ”-”. |
