CALC COMMAND ARGUMENTS
|

|

Without calc_cmd, calc operates interactively. If one or
|
||||

|

given, then calc will evaluate and execute them and then

If -i is given, calc will attempt to become interactive even

|
||||
With no calc_cmd arguments, calc operates interactively. If one
|
||||
or more arguments are given on the command line and -s is NOT
|
||||
given, then calc will read and execute them and either attempt
|
||||
to go interactive according as the -i flag was present or absent.
|
||||
|
||||
If -s is given, calc will not evaluate any calc_cmd
|
||||
arguments but instead make them available as strings to the
|
||||
argv() builtin function.
|
||||
|
||||
Normally on startup, calc attempts to execute a collection
|
||||
of resource files. The environment variable $CALCRC (if
|
||||
non-existent then a compiled in value) contains a
|
||||
: separated list of startup resource files. No error
|
||||
conditions are produced if these startup resource file are
|
||||
not found.
|
||||
Sufficiently simple commands with no no characters like
|
||||
parentheses, brackets, semicolons, '*', which have special
|
||||
interpretations in UNIX commands may be entered, possibly with
|
||||
spaces, until the terminating newline. For example:
|
||||
|
||||
If the mode disables opening of files for reading, then the
|
||||
startup resource files are disabled as of -q was given and
|
||||
$CALCRC as well as the default compiled in value are
|
||||
ignored.
|
||||
calc 23 + 47
|
||||
|
||||
Filenames are subject to ``~'' expansion (see below). The
|
||||
environment variable $CALCPATH (if non-existent then a
|
||||
compiled in value) contains a : separated list of search
|
||||
directories. If a file does not begin with /, ~ or ./, then
|
||||
it is searched for under each directory listed in the
|
||||
$CALCPATH. It is an error if no such readable file is
|
||||
found.
|
||||
should respond with display of 70, but:
|
||||
|
||||
calc 23 * 47
|
||||
|
||||
may fail. Such cases can usually be made to work as expected by
|
||||
enclosing the command between single quotation marks as in:
|
||||
|
||||
calc '23 * 47'
|
||||
|
||||
and
|
||||
|
||||
calc 'print sqrt(2), exp(1)'
|
||||
|
||||
If '!' is to be used to indicate the factorial function, for
|
||||
shells like csh for which '!' followed by a non-space character
|
||||
is used for history substitution, it may be necessary to
|
||||
include a space or use a backslash to escape the special
|
||||
meaning of '!'. For example, the command "print 27!^2" may have
|
||||
to be replaced by "print 27! ^2" or "print 27\!^2".
|
||||
|
||||
|
||||
CALC STARTUP FILES
|
||||
|
||||
Normally on startup, if the environment variable $CALCRC is
|
||||
undefined and calc is invoked without the -q flag, or if
|
||||
$CALCRC is defined and calc is invoked with -e, calc looks
|
||||
for a file "startup" in the calc resource directory, .calcrc in
|
||||
the user's home directory, and .calcinit in the current directory.
|
||||
If one or more of these are found, they are read in succession
|
||||
as calc scripts and their commands executed. When defined,
|
||||
$CALCRC is to contain a ':' separated list of names of files,
|
||||
and if calc is then invoked without either the -q or -e flags,
|
||||
these files are read in succession and their commands executed.
|
||||
No error condition is produced if a listed file is not found.
|
||||
|
||||
If the mode specified by -m disables opening of files for
|
||||
reading, then the reading of startup files is also disabled
|
||||
as if -q was given.
|
||||
|
||||
|
||||
CALC FILE SEARCH PATH
|
||||
|
||||
If the environment variable $CALCPATH is undefined, or if it
|
||||
is defined and calc is invoked with the -e flag, when a file
|
||||
name not beginning with /, ~ or ./, is specified as in:
|
||||
|
||||
calc read myfile
|
||||
|
||||
calc searches in succession:
|
||||
|
||||
./myfile
|
||||
./myfile.cal
|
||||
${LIBDIR}/myfile
|
||||
${LIBDIR}/myfile.cal
|
||||
${CUSTOMLIBDIR}/myfile
|
||||
${CUSTOMLIBDIR}/myfile.cal
|
||||
|
||||
If the file is found, the search stops and the commands in
|
||||
the file are executed. It is an error if no readable file
|
||||
with the specified name is found. An alternative search
|
||||
path can be specified by defining $CALCPATH in the same way
|
||||
as PATH is defined, as a ':' separated list of directories,
|
||||
and then invoking calc without the -e flag.
