FreeDOS help system (hhstndrd 1.0.8 en)[command]

Command: command ( or FreeCom)

COMMAND starts a new copy of the FreeDOS command shell.


COMMAND [[drive]path] [device] [/E:nnnnn] [/L:nnnn] [/U:nnn] [/P] [/MSG] [/LOW] [/Y [/[C|K] command]] COMMAND [/?] [drive]path Specifies the directory containing COMMAND.COM, e.g. C:\example\ drive The drive letter, e.g. C: path The directory, e.g. \example\ device Specifies the device to use for command input and output.


/E:nnnnn Sets the initial environment size to nnnnn bytes. (nnnnn should be between 256 and 32,768). /L:nnnn Specifies internal buffers length (requires /P as well). (nnnn should be between 128 and 1,024). /U:nnn Specifies the input buffer length (requires /P as well). (nnn should be between 128 and 255). /P Makes the new command shell permanent (can't exit). /MSG Stores all error messages in memory (requires /P as well). /LOW Forces the command shell to keep its resident data in low memory. /Y Steps through the batch program specified by /C o. /C command Executes the specified command and returns. /K command Executes the specified command and continues. /? Shows the help.


[drive]path The drive and path where the shell is to look for the transient part of the program. This is usually only needed to set the COMSPEC. device An alternate device for all i/o. /e:nnnnn The environment size, in bytes, in the range 160-32768. This number will be rounded up the nearest 16 bytes. The default is 256. /p Makes the shell permanent, so the EXIT command does not exit the shell. /c {string} Executes the command in {string}, then exits. /msg Loads any error messages that might be stored on disk into memory. COMMAND (COMMAND.COM) is also named FreeCom. It contains a lot of internal commands which need no other file in order to work. You can find the list of internal commands here.
