christos 680690d33c add type builtin. 1997-02-06 23:24:52 +00:00
christos 6f224ae59f Fix parsing problem introduced in the previous ${10} fix, where $#digit 
or $digit# would get mis-parsed as a positional parameter.

perry b195ec73d5 nuke the BUGS section -- it was vax specific 1997-01-25 00:17:00 +00:00
perry 61974fdce1 remove obsolete -d and -t options -- kernel timezone handling is long gone 1997-01-24 18:17:17 +00:00
christos 633ceb6db5 - varisset(): In positional arguments, take into account VSNUL so that: 
set -- ""; echo ${1:-wwww} works.
- when expanding arithmetic, discard previous ifs recorded regions, since we
  are doing our own scanning. x=ab; echo $((${#x}+1)) now works.
- in ${var#word} fix two bugs:
   * if there was an exact match, there was an off-by-one bug in the
     comparison of the words. x=abcd; echo ${x#abcd}
   * if there was no match, the stack region was not adjusted and the rest
     of the word was getting written in the wrong place. x=123; echo ${x#abc}X
 1997-01-24 17:26:28 +00:00
christos 3d5f212ba8 enable parsing of multi-digit positional arguments i.e. ${10} works and it 
is not a bad substitution.

mikel 6a37335a9d reference sigaction(2) instead of the obsolete sigvec(3); fixes PR 3058. 1996-12-26 02:29:58 +00:00
cjs 5678a13f1b Re-introduce some code from 1.14 (with modifications) to make the 
shell's idea of the current working directory match reality when
symlinks (or anything else we can't stat) are traversed with the
cd command. However, this does not print out the cwd after cd
traverses symlinks, as it used to, though the capability is still
there should one want to use it.

christos 340077b543 - fix parsing bug reported by mycroft: ! was only recognized in the beginning 
of pipelines. Now we are recognizing it everywhere like ksh, so:

	! if [ a = b ]; then ! echo c && ! true; else ! echo d; fi

  works.
