The /bin/sh in both 3.2-STABLE and 4.0-CURRENT produce the expected
results:
$f=/tmp/user/wpage.html
${f%.*}=/tmp/user/wpage
${f%/*}=/tmp/user
${f%"/wpage.html"}=/tmp/user
"$f"=/tmp/user/wpage.html
"${f%.*}"=/tmp/user/wpage
"${f%/*}"=/tmp/user
"${f%"/wpage.html"}"=/tmp/user
Time to upgrade? :-)
Ciao,
Sheldon.

I submitted the bug report from an account at my ISP, though, and they will have a difficult time upgrading from 2.2.8 without breaking many customers' CGIs.

The expansion of a Bourne shell parameter with a pattern to be removed produces garbage characters in place of the removed pattern when the pattern includes a slash, and the whole expansion string is quoted. Fix: unknown How-To-Repeat: Run this script: #!/bin/sh f=/tmp/user/wpage.html echo '$f='$f echo '${f%.*}='${f%.*} echo '${f%/*}='${f%/*} echo '${f%"/wpage.html"}='${f%"/wpage.html"} echo '' echo '"$f"='"$f" echo '"${f%.*}"='"${f%.*}" echo '"${f%/*}"='"${f%/*}" echo '"${f%"/wpage.html"}"='"${f%"/wpage.html"}" The last two echos output garbage in place of the trailing pattern which was removed.
