The cureent implementation of /usr/bin/pwd doesn't care about arguments. $ /usr/bin/pwd -G -A -R -B -A -G _E /tmp/gisburn The ksh93 builtin version of "pwd" issues an error for everything except -L and -P, however -P is a no-op since this is a seperate process which only sees the physical path at startup. > Output format: path name on a single line > > Are you changing any of those? Since you said to drop the suggestion to > use -P & -L, it sounds like you're not. See above. The current implementation just ignores all switches and the new one would ignore -L and -P switches and issue errors for all other options. This may be a border case since pwd(1) does not describe any options or the behaviour if any options are given. Existing scripts won't be affected as they usually do not pass any arguments to /usr/bin/pwd and if they do it's likely either -P or -L where the resulting behaviour is identical to the current /usr/bin/pwd > That leaves imported interfaces.

Ok... this is the point where I need April or Don (since I cause almost everytimes havov&&destruction)... libshell is "Project Private" - but in which scope... "OS/Net" or "ksh93-integration" ? ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;)
