Message-ID: <46F23395.7030305@sbcglobal.net> (raw)
Is there any way to make "pushd" and "popd" (Bash built-ins) silent? As
it is, when the execute, the directory is echoed to the output, making
it difficult to use the commands in a script. For example:
OLD_VER=$(pushd /boot; ls kernel-* | sort | head -1; popd)
echo $OLD_VER
/boot ~ kernel-2.6.22-gentoo-r2 ~
The /boot and the tildes are returned by pushd and popd and mess up the
script.
There doesn't seem to be any options to turn off the echo off and shopt
has nothing in it.
