>Description:
Tab completion in /bin/sh can be enabled with "set -o tabcomplete".
In most shells, tab completion is syntax sensitive, at least to the
extent that it offers different completions for commands and
non-commands. In /bin/sh, tab completion always attempts to
complete a file name.
>How-To-Repeat:
For example, in ksh:
ksh$ set -o emacs
ksh$ cd /tmp ; touch pw1 pw2 pw3
# type "pw" then press TAB
ksh$ pw[TAB]
# ksh displays some command names starting with "pw"
pwd pwd_mkdb pwhash pwhich
ksh$ pw
but in /bin/sh, the tab completion is much less useful:
sh$ set -o emacs ; set -o tabcomplete
sh$ cd /tmp ; touch pw1 pw2 pw3
# type "pw" then press TAB
sh$ pw[TAB]
# sh attempts to treat "pw" as the start of a file name,
# not as the start of a command name. It changes the
# "pw" to "./pw". Press TAB again. and ./pw is expanded
# to a list of file names:
sh$ ./pw[TAB]
./pw1 ./pw2 ./pw3
sh$ ./pw
>Fix:
Make tab completion work with command names, not file names,
for the first word on a line, the first word after ';', '|',
'||', '&&', and any other contexts where it's known that
the word must be a command.
