Not sure if this is a bug or not, so here goes: I was trying to figure out why I was having trouble with nt4 seeming to hang when I pass a long list of args to a command. The following command works just fine.
echo *.o > foo.txt
The above produces a file that is 1918 characters long; no delay. There are
86 files. The following,
ls *.o
just hangs and bumps the cpu to 100%. Same deal with
ls * rm *.o
On the other hand, the following completes instantly:
ls -lrt
Further, I was able to do this
ls [ab]*.o - this worked
and this,
ls [c]*.o - this worked
but not
ls [bc]*.o - this hanged
It seems like if the path args get too long, bad stuff happens. Same thing
happens in tcsh as well as bash. Any ideas?
I've attached cygcheck.out as well the file "foo.txt", which contains the
list of file names.
Context: I originally noticed this problem as part of a unix makefile hang.
Part of the "make clean" was to do an "rm *.o". Changing this to "rm
$(OBJS)" didn't work, but changing to "rm $(OBJS1)", "rm $(OBJS2)", and "rm
$(OBJS3)" worked fine.
<<cygcheck.out>> <<foo.txt>>
cygcheck.out
