Tim J. Robbins 3771ef59ae Move job to front of most recently used job list when bg'd or fg'd. 2002-05-31 12:35:34 +00:00
Tim J. Robbins d86825beb8 Instead of keeping just the jobid of the most recently bg'd or fg'd job, 
keep a linked list of the jobs, most recently used first. This is required
to support the idea of `previous job', and to allow the jobs fg and bg
default to be correct according to POSIX.

Tim J. Robbins 09086b0499 Bring back the cd -L and -P options from revision 1.24, but try harder not 
to fail when the logical current directory no longer exists. Allow changes
to absolute paths when logical cwd is invalid, fall back to physical cd
if logical cd fails.
 2002-05-22 05:15:53 +00:00
Tim J. Robbins baf3e7c14b Temporarily back out revision 1.24; it seems to handle the case where the 
current directory no longer exists incorrectly and breaks `make cleandir'.

Tim J. Robbins 178897f127 Add the SUSv3 -L and -P options to the cd and pwd builtin utilities. `Logical'

Tim J. Robbins addcdbb29f Make the fg and bg commands give the output required by SUSv3. 
fg outputs the name of the command, bg outputs the name of the command
and the job id.

Tim J. Robbins 1a958c6653 Implement the -C (-o noclobber) option, which prevents existing regular
