The default is {} ehysical size of

socket .blocks used in data transmission.

The default can be specified via the {t SK_bsk} environment

variable; if {t SK_bsk} is not defined, the default

depends on the socket standards, generally 4K. - {\m prompt}} defines the prompt to be displayed in

case of interactive mode. The default is \

used as a separate argument to delimit commands.

When no {\m command} is given

as arguments, gm waits for commands in the {\m standard input}.

nsec{ Sending or Capturing the Data }

Data are normally transferred via the {\m standard} input and

output. A first solution therefore consists

in specifying the command for data transfer as {\m options}, e.g.

gm {t {\m host} {\m service_file} Write /tmp/copy < myinput} s h }

There are redirection possibilities but unlike {(

these 1 ) redirections must be specified {\m before} the command.

The g i n { example above could be executed as:

rdright}

gm a g g {t {\m host} {\m service_file} }\

{t{\m host}/{\m service_file}$>$} {t <myinput Write /tmp/copy}\

{t{\m host}/{\m service_file}$>$} ots

\nd{raggedright}

Note that file names may be replaced by pipes for names starting

with the $|$ character; if blanks are embedded, the command have

to be quoted. For instance, to write the list g i n { of files

to a foreign file:

rdright}

gm a g g {t {\m host} {\m service_file} }\

{t{\m host}/{\m service_file}$>$}{t <"|ls -l" Write /tmp/copy}\

{t{\m host}/{\m service_file}$>$} ots

\nd{raggedright} a c l i e n t } c

nsec{Escaping conventions}

Since {o

is executed, a n n e c t s t o { special convention (similar to http queries)

is available to {\m escape} special characters and

define arguments with special characters to the server

program. This convention . . . } uses {tine

parameters with special characters (like blank, o d e asterisks, etc).
