New variables $OSTYPE, $MACHTYPE, $VENDOR similar + to the gnu ones. +* $< can be interrupted and takes modifiers.

The history file contains + now the timestamps as csh comments. + + +6.02 +* ignore_symlinks and chase_symlinks are replaced with symlinks=ignore + and symlinks=chase; symlinks=expand addition +* complete and uncomplete builtins; user-programmable completion additions. +* Tcsh now uses the rightmost column of the terminal, allowing cut-and-paste + operations in terminal emulators that work [xterm R5 not R4] +* echo_style controls now the behaviour of the builtin echo; the default + should match the builtin echo of /bin/csh; if your system does not + come with csh, then the default echo should match /bin/echo. +* cd -; changes to the previous directory. +* setting dunique variable pushes only unique directories on the directory + stack. +* source builtin allows additional arguments that get passed in $argv in + the sourced script. +* tcsh now mirrors correctly all exported csh variables [term=TERM,path=PATH + etc.] +* showdots=-A makes listing behave like ls -A. +* directory stack access = allows for entries > 9. +* $a:u uppercase the first character in $a, $a:l downcases the first + character in $a. +* Shorthand for file tests in 'if' expressions ( -dx file ) is the + same as ( -d file && -x file ) + +6.01 +* Nothing new. + +6.00 PL3 +* %d in the prompt is the week-day and no longer $cwd; use %/ instead. +* changes in the prompt format. Date changes to accomodate people from + down under. +* vi insert mode to command mode transition does not move the cursor. + +6.00 PL2 +* setty builtin + This is used to specify what tcsh modes can be altered using stty, + Modes that should be set are specified as +, modes that should + be cleared are specified as -, and the ones that should be + untouched are specified as . setty with no arguments prints + the modes that are affected by tcsh, and setty -a prints all modes. +* multiple : modifiers in variables and ! escapes. Things like: + > set prompt="$host:r:$cwd>" + don't work any more, they should be replaced with + > set prompt="${host:r}:$cwd>" + or + > set prompt="$host:r"":$cwd>" + the reason is that now you can + > set foo=/usr/local/a.b.c + > echo $foo:t:r:e + b + If for some reason you don't like this change you can disable it with + -DCOMPAT. -DCOMPAT may go away in future tcsh versions and the way tcsh + works now is the way the 4.4BSD csh works. + +6.00 PL1 +* There is no more config.iris4d, use config.sgi instead + +6.00 +* History searching searches using shell patterns too. +* The autolist values that controlled beeping are not supported any more; + used matchbeep instead. +* /etc/Login and /etc/Logout were renamed to /etc/csh.login /etc/csh.logout + and /etc/csh.cshrc was added +* prompt2 and prompt3 can have prompt escapes. +* eval pipes work +* ignore_symlinks works + +5.20 PL2 +* %{..%} escapes in prompt + +5.20 PL0 +* bindkey -r +* history -t +* shell variables in paths expand correctly. +* variable expansion +* quoted expansions now work. +* new version and tcsh variable format + +5.19 PL2 +* NLS support +* New bindkey and echotc builtins +* Underline and Bold in the prompt; additions and changes to the prompt and + who syntax (%u is now %n, so that %u can be used to turn undeline off, + and %n is now \n). +* rmstar needs to be set to protect from accidental removal +* Fixed editor, and spell line. +* Glob-expand, on arguments. +* Added process migration builtins for aix370 + +5.19 PL1 +* Maintainance release for mainly the rs6000 + +5.19 PL0 +* 8 bit clean code, by using 16 bit strings. +* Mostly shared strings (a side-effect) +* Highlights everywhere (and in ls-F) filenames that contain characters + with the eighth bit set (or passes them unchanged depending on the + variable 'nometa') +* Newline in the prompt via %n. +* dirs takes also a -v flag for `vertical display' +* There is a new variable `listjobs' which controls if and how jobs + are displayed when a new job is suspended.
