Q: Bash crashes on me when I invoke shell scripts....
Q: Why does Bash say "pipe error: Access denied" when I try to run
two programs via a pipe?
Q: When I run certain complex shell scripts, Bash sometimes prints a
message saying "Cannot make a child for command substitution:
(null)". What gives??
Q: What does it mean when Bash says "Can't make pipes for command
A: If Bash crashes when you invoke shell scripts, check whether
those scripts have
#!/bin/sh on their first line. If they do,
the most probable reason for the crashes is that you don't have
sh.exe anywhere on your
PATH (it does not have to
/bin!). Either copy
create a "symlink" to
bash.exe, like this:
ln -s c:/djgpp/bin/bash.exe c:/djgpp/bin/sh.exe
c:/djgpp with the actual pathname of your DJGPP
Error messages about pipes and command substitution usually mean that
TMPDIR environment variable points to an invalid drive; make
TMPDIR is set and points to an existing directory, and that
the drive where it points is writable and not full. Old ports of Bash
had problems with
`command` substitution, so make sure you have
the latest binaries.
