1This file contains visible (incompatible) changes to the users. 2This version of tcsh has the following new things: 3 46.08 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. 10 116.07 12* Implicit cd when the variable implicitcd is set or set to verbose 13 146.06 15* NLS Message Catalog support. 16 176.05 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 21* new hup builtin 22* =x obeys nonomatch 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 27 to the gnu ones. 28* $< can be interrupted and takes modifiers. Does not quote args by default 29 like csh. 30 316.04 32* Variable modifiers do not stop processing after the first one fails 33 > set i=aabbcc 34 > echo $i:s/a/A/:s/b/B/ 35 AaBbcc 36 > echo $i:s/x/A/:s/b/B/ 37 aabbcc 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. 43 446.03 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. 56* builtins builtin. 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. 62 63 646.02 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 75 stack. 76* source builtin allows additional arguments that get passed in $argv in 77 the sourced script. 78* tcsh now mirrors correctly all exported csh variables [term=TERM,path=PATH 79 etc.] 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 83 character in $a. 84* Shorthand for file tests in 'if' expressions ( -dx file ) is the 85 same as ( -d file && -x file ) 86 876.01 88* Nothing new. 89 906.00 PL3 91* %d in the prompt is the week-day and no longer $cwd; use %/ instead. 92* changes in the prompt format. Date changes to accomodate people from 93 down under. 94* vi insert mode to command mode transition does not move the cursor. 95 966.00 PL2 97* setty builtin 98 This is used to specify what tcsh modes can be altered using stty, 99 Modes that should be set are specified as +<mode>, modes that should 100 be cleared are specified as -<mode>, and the ones that should be 101 untouched are specified as <mode>. setty with no arguments prints 102 the modes that are affected by tcsh, and setty -a prints all modes. 103* multiple : modifiers in variables and ! escapes. Things like: 104 > set prompt="$host:r:$cwd>" 105 don't work any more, they should be replaced with 106 > set prompt="${host:r}:$cwd>" 107 or 108 > set prompt="$host:r"":$cwd>" 109 the reason is that now you can 110 > set foo=/usr/local/a.b.c 111 > echo $foo:t:r:e 112 b 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. 116 1176.00 PL1 118* There is no more config.iris4d, use config.sgi instead 119 1206.00 121* 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. 127* eval pipes work 128* ignore_symlinks works 129 1305.20 PL2 131* %{..%} escapes in prompt 132 1335.20 PL0 134* bindkey -r 135* history -t 136* shell variables in paths expand correctly. 137* variable expansion 138* quoted expansions now work. 139* new version and tcsh variable format 140 1415.19 PL2 142* NLS support 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, 146 and %n is now \n). 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 151 1525.19 PL1 153* Maintainance release for mainly the rs6000 154 1555.19 PL0 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 160 variable 'nometa') 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 166 the same job!] 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. 170
