tcsh
Table 32. tcsh Built-in Shell Variables (continued)
Variable Purpose
listflags If set to x, a or A, or any combination thereof (for
example, xA), they are used as flags to ls-F, making it
act like ls -xF, ls -Fa, ls -FA or a combination (for
example, ls -FxA): a shows all files (even if they start
with a ’.’), A shows all files but ’.’ and ’..’, and x sorts
across instead of down. If the second word of listflags is
set, it is used as the path to ls(1).
listjobs If set, all jobs are listed when a job is suspended. If set
to long, the listing is in long format.
listlinks If set, the ls-F built-in command shows the type of file to
which each symbolic link points. For an example of its
use, see “ls-F built-in command for tcsh: List files” on
page 685.
listmax The maximum number of items which the list-choices
editor ocmmand will list without asking first.
listmaxrows The maximum number of rows of items which the
list-choices editor command will list without asking first.
loginsh Set by the shell if is a login shell. Setting or unsetting it
within a shell has no effect. See also shlvl.
logout Set by the shell to normal before a normal logout,
automatic before an automatic logout, and hangup if the
shell was killed by a hangup signal (see “Signal handling”
on page 652). See also the autologout shell variable.
mail The names of the files or directories to check for
incoming mail, separated by whitespace, and optionally
preceeded by a numeric word. Before each prompt, if 10
minutes have passed since the last check, the shell
checks each file and says ’You have new mail.’ (or, if mail
contains multiple files, ’You have new mail in name.’) if
the filesize is greater than zero in size and has a
modification time greater than its access time.
If you are in a login shell, then no mail file is reported
unless it has been modified after the time the shell has
started up, in order to prevent redundant notifications.
Most login programs will tell you whether or not you have
mail when you log in.
If a file specified in mail is a directory, the shell will count
each file within that directory as a separate message,
and will report ’You have n mails.’ or ’You have n mails in
name.’ as appropriate. This functionality is provided
primarily for those systems which store mail in this
manner, such as the Andrew Mail System.
If the first word of mail is numeric it is taken as a different
mail checking interval, in seconds. Under very rare
circumstances, the shell may report ’You have mail.’
instead of ’You have new mail.’
matchbeep If set to never, completion never beeps. If set to
nomatch, it beeps only when there is no match. If set to
ambiguous, it beeps when there are multiple matches. If
set to notunique, it beeps when there is one exact and
other longer matches. If unset, ambiguous is used.
