Yet Another Shell

Fork

Yet another shell, version 2.8.

Conforms to POSIX.1-2008 (previous versions conformed POSIX.1-2001), and includes some new features, spec change, and bug fixes.

Yash 2.8

+ Brace expansion with delta: {a..b..c}
+ The "command" builtin's -b and -B options now can be used with the -v and -V options.
= Yash now conforms to POSIX.1-2008.
. The "read" builtin now always removes trailing white-spaces from the input.
. The results of tilde expansion are no longer subject to field splitting and pathname expansion.
. The "pwd" builtin with the -P option no longer sets the $PWD variable.
. "cd -L foo/.." is no more the same as "cd -L ." in that it is an error when the directory "foo" does not exist.
. The "command" builtin's -p option now can be used with the -v and -V options.
. In posixly-correct mode, all asynchronous commands now ignore SIGINT and SIGQUIT (even when job control is active).
* When executing commands edited by the "fc" builtin, the $? variable was incorrectly assigned the exit status of the editor invoked by "fc".
* Backslashes, commas and braces in $IFS were incorrectly ignored in field splitting.
* Pathname expansion failed if we do not have the read permission for the specified directory even when we only need the search permission.
* The signal mask of commands invoked by the shell now inherits that of the shell (except for trapped signals).
* The "command" builtin now properly handles directories given as the commands when the "autocd" option is on.
