In particular, it was created +in order to cope with the problem of missing shared libraries or important +executables. + +Sash can execute external programs, as in any shell. There are no +restrictions on these commands, as the standard shell is used to execute +them if there are any non-wildcard meta-characters in the command. +More importantly, however, is that many of the standard system commands +are built-in to sash. + +This script applies the 'sash-plus-patches' command collection, which +adds the following commands: 'chroot' 'pivot_root' and 'losetup'. + +These functions actually provide interfaces to the respective Linux system +calls. They are specificly useful when sash is used as a shell in "initial +ramdisk" (initrd) environments. + +In addition, a simple shell variable expansion support has been added, e.g. +the variable "$(VAR)" is replaced by the content of the variable "VAR". diff --git a/system/sash/doinst.sh b/system/sash/doinst.sh new file mode 100644 index 000000000000..e5dccd90cc02 --- /dev/null +++ b/system/sash/doinst.sh @@ -0,0 +1,7 @@ +#!/bin/sh + +# Add sash to the shells if not there +if ! grep -q "/sash$" etc/shells ;
