Edit File: NewThings
This file contains visible (incompatible) changes to the users. This version of tcsh has the following new things: 6.08 * %$variables are now expanded in the prompt. * print_by_columns prints in a single column if the output is not a tty. * REMOTEHOST contains only the IP address, not the host name of the machine. * names in .cshdirs are quoted. * exit value from 0..255 not -128..127 as posix mandates. 6.07 * Implicit cd when the variable implicitcd is set or set to verbose 6.06 * NLS Message Catalog support. 6.05 * The bind, aliases, linedit builtins are not used anymore; they are #ifdef'ed OBSOLETE and will be really removed in the next version * new filetest builtin * new hup builtin * =x obeys nonomatch * tcsh.man2html nroff to HTML converter for the tcsh manpage * prompt is now %# by default. * $REMOTEHOST contains the name of the remote host (optional) * $HOSTTYPE is going away. New variables $OSTYPE, $MACHTYPE, $VENDOR similar to the gnu ones. * $< can be interrupted and takes modifiers. Does not quote args by default like csh. 6.04 * Variable modifiers do not stop processing after the first one fails > set i=aabbcc > echo $i:s/a/A/:s/b/B/ AaBbcc > echo $i:s/x/A/:s/b/B/ aabbcc * set -r makes variables readonly * set nonomatch, echo ~notaser returns ~notauser instead of an error * file operators: Changed -s == !-z and -S == socket * $?0 returns false now on interactive shells for csh compatibility. * %p%P include seconds in prompt strings. 6.03 * $%var contains the number of characters in $var. * Shell -w -x are now POSIX compliant on POSIX machines. * Imported environment variables are not globbed. * $dirstack can be used to set and examine the directory stack. * $? == $status and $# == $#argv like in the bourne shell. * expand variables expands arrays too (but not array elements yet). * $0 contains argv[0] on interactive shells. * new -b -c etc file operators from SGI csh. * nostat takes a list of shell patterns. * symbolic names for arrow key bindings [left, right, up, down] * shift, left operators update variables correctly. * builtins builtin. * history and dirs accept now -LSc flags. * $history accepts an optional second argument, that can change the history builtin output similar to the $time format. * History timestamps preserved in .history. 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 =<num> 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 $cwd; use %/ instead. * changes in the prompt format. Date changes to accomodate people from down under. * vi insert mode to command mode transition does not move the cursor. 6.00 PL2 * setty builtin This is used to specify what tcsh modes can be altered using stty, Modes that should be set are specified as +<mode>, modes that should be cleared are specified as -<mode>, and the ones that should be untouched are specified as <mode>. setty with no arguments prints the modes that are affected by tcsh, and setty -a prints all modes. * multiple : modifiers in variables and ! escapes. Things like: > set prompt="$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. [Idea from the mtXinu code, very useful for novice users who hit control-Z 10 times on the same job!] set listjobs=long, jobs -l is executed every time a job is suspended. set listjobs=short, jobs is executed every time a job is suspended. * Passes lint... At least on a sun.
