Executes command for each matching file ----------------------------

^forfile^ [filespec] [ ^, d^ir^(^directory^) a^sis ^l^ist cmd('" cmd1 @ | c > md2 @ "') more]

Description -----------

^forfile^ executes a command for each file matching a file pattern. If no command is specified, it does -graph using- If no filespec is specified, it uses *.gph

filespec can take one of the following forms:

(nothing) -- treated as ^*.gph^ ^*^ ^*.gph^ ^*.gph^ ^*.gph^ name name^.gph^ name.^gph^ name^.gph^ name^*^ name^*.gph^ name^*.gph^ name^*.gph^

Options -------

^dir(^directory^)^ specifies a directory or folder in which to look. The default is the current directory as indicated by ^cd^.

^asis^ specifies that graphs should be shown as is. By default, each graph is shown with its filename shown as a ^t1title^. ^asis^ turns off this feature.

^list^ specifies that graph filenames should be listed in alphanumeric order. Note that by default (and necessarily) the results of a ^dir^ command are shown on the monitor, although not necessarily in alphanumeric order.

^cmd^ executes this command for each file. Put @ where you want the file name replaced Put | as separators between commands

Remarks -------

Except under Unix, any log file open when ^showgph^ is invoked is closed temporarily, and the results of a call to ^dir^ are logged to a temporary file. Thus such results will not be shown in the log file. The ^list^ option should be used if it is desired to have a list of graph filenames in the current log file.

Under Unix, the system ^ls^ is used to write to a temporary file and any log file open is not affected.

Examples --------

. ^forfile *.gph , cmd(`"graph using "@" "')^ . ^forfile *.gph , d(\a\folder\) cmd(`"graph using "@" | gphprint"')^
