- Subject: bash 3.2.49-22 problem (subscripts fail to run sometimes)
Occasionally, a subscript fails to run, as in this example:
$ cat t.sh
#!/bin/bash
PACKAGEVERSION=$1
PACKAGE=`echo $PACKAGEVERSION | sed 's/^\(.*\)-.*$/\1/'`
VERSION=`echo $PACKAGEVERSION | sed 's/^.*-\(.*\)$/\1/'`
echo "PACKAGE $PACKAGE VERSION $VERSION"
PACKAGE=`echo $PACKAGEVERSION | sed 's/^\(.*\)-.*$/\1/'`
VERSION=`echo $PACKAGEVERSION | sed 's/^.*-\(.*\)$/\1/'`
echo "PACKAGE $PACKAGE VERSION $VERSION"
PACKAGE=`echo $PACKAGEVERSION | sed 's/^\(.*\)-.*$/\1/'`
VERSION=`echo $PACKAGEVERSION | sed 's/^.*-\(.*\)$/\1/'`
echo "PACKAGE $PACKAGE VERSION $VERSION"
$ ./t.sh Hello-1.0.0
PACKAGE Hello VERSION 1.0.0
PACKAGE Hello VERSION
PACKAGE Hello VERSION 1.0.0
$ ./t.sh Hello-1.0.0
PACKAGE Hello VERSION 1.0.0
PACKAGE Hello VERSION 1.0.0
PACKAGE VERSION 1.0.0
This is under Cygwin 1.5.25-15 under Windows XP Ver. 5.1 Build 2600
Service Pack 2.
This is easily repeatable. I run into the problem by running the
script 4 to 6 times.
Is this a Cygwin bash bug? I wonder if it's related to running on a
multi-core processor. I don't have the problem under Linux.
Sincerely,
Vitas Povilaitis
