- Environment variables
-
- CALCPATH
-
- A :-separated list of directories used to search for
- scripts filenames that do not begin with /, ./ or ~.
-
- If this variable does not exist, a compiled value
- is used. Typically compiled in value is:
-
- .:./lib:~/lib:${LIBDIR}/calc
-
- where ${LIBDIR} is usually:
-
- /usr/lib/calc
-
- This value is used by the READ command. It is an error
- if no such readable file is found.
-
-
- CALCRC
-
- On startup (unless -h or -q was given on the command
- line), calc searches for files along the :-separated
- $CALCRC environment variable.
-
- If this variable does not exist, a compiled value
- is used. Typically compiled in value is:
-
- ${LIBDIR}/startup:~/.calcrc
-
- where ${LIBDIR} is usually:
-
- /usr/lib/calc
-
- Missing files along the $CALCRC path are silently ignored.
-
- CALCBINDINGS
-
- On startup (unless -h or -q was given on the command
- line), calc reads key bindings from the filename specified
- in the $CALCRC environment variable. These key bindings
- are used for command line editing and the command history.
-
- If this variable does not exist, a compiled value is used.
- Typically compiled in value is:
-
- ${LIBDIR}/bindings
-
- where ${LIBDIR} is usually:
-
- /usr/lib/calc
-
- If the file could not be opened, or if standard input is not
- a terminal, then calc will still run, but fancy command line
- editing is disabled.
-
- HOME
-
- This value is taken to be the home directory of the
- current user. It is used when files begin with '~/'.
-
- If this variable does not exist, the home directory password
- entry of the current user is used. If that information
- is not available, '.' is used.
-
- PAGER
-
- When invoking help, this environment variable is used
- to display a help file.
-
- If this variable does not exist, a compiled value
- is used. Typically compiled in value is something
- such as 'more', 'less', 'pg' or 'cat'.
-
- SHELL
-
- When a !-command is used, the program indicated by
- this environment variable is used.
-
- If this variable does not exist, a compiled value
- is used. Typically compiled in value is something
- such as 'sh' is used.
