1 This file contains visible (incompatible) changes to the users.
2 This version of tcsh has the following new things:
5 * %$variables are now expanded in the prompt.
6 * print_by_columns prints in a single column if the output is not a tty.
7 * REMOTEHOST contains only the IP address, not the host name of the machine.
8 * names in .cshdirs are quoted.
9 * exit value from 0..255 not -128..127 as posix mandates.
12 * Implicit cd when the variable implicitcd is set or set to verbose
15 * NLS Message Catalog support.
18 * The bind, aliases, linedit builtins are not used anymore; they are
19 #ifdef'ed OBSOLETE and will be really removed in the next version
20 * new filetest builtin
23 * tcsh.man2html nroff to HTML converter for the tcsh manpage
24 * prompt is now %# by default.
25 * $REMOTEHOST contains the name of the remote host (optional)
26 * $HOSTTYPE is going away. New variables $OSTYPE, $MACHTYPE, $VENDOR similar
28 * $< can be interrupted and takes modifiers. Does not quote args by default
32 * Variable modifiers do not stop processing after the first one fails
34 > echo $i:s/a/A/:s/b/B/
36 > echo $i:s/x/A/:s/b/B/
38 * set -r makes variables readonly
39 * set nonomatch, echo ~notaser returns ~notauser instead of an error
40 * file operators: Changed -s == !-z and -S == socket
41 * $?0 returns false now on interactive shells for csh compatibility.
42 * %p%P include seconds in prompt strings.
45 * $%var contains the number of characters in $var.
46 * Shell -w -x are now POSIX compliant on POSIX machines.
47 * Imported environment variables are not globbed.
48 * $dirstack can be used to set and examine the directory stack.
49 * $? == $status and $# == $#argv like in the bourne shell.
50 * expand variables expands arrays too (but not array elements yet).
51 * $0 contains argv[0] on interactive shells.
52 * new -b -c etc file operators from SGI csh.
53 * nostat takes a list of shell patterns.
54 * symbolic names for arrow key bindings [left, right, up, down]
55 * shift, left operators update variables correctly.
57 * history and dirs accept now -LSc flags.
58 * $history accepts an optional second argument, that can change the
59 history builtin output similar to the $time format.
60 * History timestamps preserved in .history. The history file contains
61 now the timestamps as csh comments.
65 * ignore_symlinks and chase_symlinks are replaced with symlinks=ignore
66 and symlinks=chase; symlinks=expand addition
67 * complete and uncomplete builtins; user-programmable completion additions.
68 * Tcsh now uses the rightmost column of the terminal, allowing cut-and-paste
69 operations in terminal emulators that work [xterm R5 not R4]
70 * echo_style controls now the behaviour of the builtin echo; the default
71 should match the builtin echo of /bin/csh; if your system does not
72 come with csh, then the default echo should match /bin/echo.
73 * cd -; changes to the previous directory.
74 * setting dunique variable pushes only unique directories on the directory
76 * source builtin allows additional arguments that get passed in $argv in
78 * tcsh now mirrors correctly all exported csh variables [term=TERM,path=PATH
80 * showdots=-A makes listing behave like ls -A.
81 * directory stack access =<num> allows for entries > 9.
82 * $a:u uppercase the first character in $a, $a:l downcases the first
84 * Shorthand for file tests in 'if' expressions ( -dx file ) is the
85 same as ( -d file && -x file )
91 * %d in the prompt is the week-day and no longer $cwd; use %/ instead.
92 * changes in the prompt format. Date changes to accomodate people from
94 * vi insert mode to command mode transition does not move the cursor.
98 This is used to specify what tcsh modes can be altered using stty,
99 Modes that should be set are specified as +<mode>, modes that should
100 be cleared are specified as -<mode>, and the ones that should be
101 untouched are specified as <mode>. setty with no arguments prints
102 the modes that are affected by tcsh, and setty -a prints all modes.
103 * multiple : modifiers in variables and ! escapes. Things like:
104 > set prompt="$host:r:$cwd>"
105 don't work any more, they should be replaced with
106 > set prompt="${host:r}:$cwd>"
108 > set prompt="$host:r"":$cwd>"
109 the reason is that now you can
110 > set foo=/usr/local/a.b.c
113 If for some reason you don't like this change you can disable it with
114 -DCOMPAT. -DCOMPAT may go away in future tcsh versions and the way tcsh
115 works now is the way the 4.4BSD csh works.
118 * There is no more config.iris4d, use config.sgi instead
121 * History searching searches using shell patterns too.
122 * The autolist values that controlled beeping are not supported any more;
123 used matchbeep instead.
124 * /etc/Login and /etc/Logout were renamed to /etc/csh.login /etc/csh.logout
125 and /etc/csh.cshrc was added
126 * prompt2 and prompt3 can have prompt escapes.
128 * ignore_symlinks works
131 * %{..%} escapes in prompt
136 * shell variables in paths expand correctly.
138 * quoted expansions now work.
139 * new version and tcsh variable format
143 * New bindkey and echotc builtins
144 * Underline and Bold in the prompt; additions and changes to the prompt and
145 who syntax (%u is now %n, so that %u can be used to turn undeline off,
147 * rmstar needs to be set to protect from accidental removal
148 * Fixed editor, and spell line.
149 * Glob-expand, on arguments.
150 * Added process migration builtins for aix370
153 * Maintainance release for mainly the rs6000
156 * 8 bit clean code, by using 16 bit strings.
157 * Mostly shared strings (a side-effect)
158 * Highlights everywhere (and in ls-F) filenames that contain characters
159 with the eighth bit set (or passes them unchanged depending on the
161 * Newline in the prompt via %n.
162 * dirs takes also a -v flag for `vertical display'
163 * There is a new variable `listjobs' which controls if and how jobs
164 are displayed when a new job is suspended. [Idea from the mtXinu
165 code, very useful for novice users who hit control-Z 10 times on
167 set listjobs=long, jobs -l is executed every time a job is suspended.
168 set listjobs=short, jobs is executed every time a job is suspended.
169 * Passes lint... At least on a sun.
