NAME
dtenvvar — CDE environment variables

DESCRIPTION

The CDE desktop sets up and uses a number of environment variables to find certain files and do certain things. Components tied into CDE then use these environment variables to locate specific types of files. Environment variables used within the CDE desktop are:

CEPATH

COLUMNS
    Set by the terminal emulator. Refer to dtterm(1) for more information.

DISPLAY
    Is set to the associated display name. Refer to dtlogin(1) and ttsession(1) for more information.

DTAPPSEARCHPATH
    Used to search for Application Manager applications. Refer to dtappgather(1) and dtsearchpath(1) for more information.

DTDATABASESEARCHPATH
    Used to collect filetype and action definitions, as expressed in *.dt files. Refer to dtsearchpath(1), dtaction(1), dtactionfile(4), and dtdtsfile(4) for more information.

DTHELPSEARCHPATH
    System specified variable used to locate desktop help files. Refer to dtsearchpath(1) and dthelpgen(1) for more information.

DTHELPUSERSEARCHPATH
    User specified variable used to locate desktop help files. Refer to dtsearchpath(1) and dthelpgen(1) for more information.

DTINFOLIBSEARCHPATH
    Used by dtinfo to locate information libraries on local and remote mounted systems. Refer to dtsearchpath(1) and dtdocbook2infolib(1) for more information.

DTINFOLIBDEFAULT
    Used by dtinfo to identify the default information library(s) to load if the -l or -sect option is not specified. Multiple information libraries can be specified by a comma separated list. By default, DTINFOLIBDEFAULT is initialized to the CDE infolib cde.

DTMOUNTPOINT
    Used to set the name of the file system's mount point, such as '/nfs' or '/net'. Refer to dtspcd(1m) and dtsearchpath(1) for more information.

DTPRINTCWD
    If set to an existing, usable directory, this setting causes dtlp(1) to execute the lp command pipeline from that directory. By default, this setting uses the current directory from which dtlp(1) is invoked. Refer to dtlp(1) for more information.

DTPRINTFILEREMOVE
    Remove the file after printing it. This functionality is intended for temporary files generated by components such as the Text Editor and Help system files that don't need to persist beyond the act of printing. Value must be True or False (case is ignored). Default is False. Refer to dtlp(1) for more information.

DTPRINTSILENT

It is the primary environment variable and drives the remaining search paths for filetypes and actions, for desktop icons, and for help files. Refer to dtappgather(1) and dtsearchpath(1) for more information.

DTSPSYSDATABASEHOSTS
