Hi. I am referring to the autoconf manual that I found on savannah.org under path /autoconf/manual/autoconf-2.63. Some more issues, continuing the list I started in my previous mail: Issue 3: --------- Another reason to be careful with "set -e" on Solaris 10: A failing command substitution may not be caught by any means if option "-e" is set. The shell bails out immediately: $ ( set -e; foo=`false` || echo "foo"; echo "bar" ); echo "baz" baz Issue 4: --------- Older Bashes (mine is 2.05b.0(1)) may forget exit values if there is a trap on exit set and if the trap consists of one succeeding external command only. Seems to be fixed in latest Bashes. $ /bin/bash -c 'trap "/bin/true" 0; exit 2'; echo $? 0 $ /bin/bash -c 'trap ":; /bin/true" 0; exit 2'; echo $? 2 I hit that problem when I had a "rm -f " clean-up trap in a canned sequence in a makefile, where the sequence failed but "make" did not take any notice of that fact due to this bug ... not too exotic an use-case, I think.
