Is there any way to make "pushd" and "popd" (Bash built-ins) silent? As |
| 2 |
it is, when the execute, the directory is echoed to the output, making |
| 3 |
it difficult to use the commands in a script. For example: |
| 4 |
|
| 5 |
OLD_VER=$(pushd /boot; ls kernel-* | sort | head -1; popd) |
| 6 |
echo $OLD_VER |
| 7 |
/boot ~ kernel-2.6.22-gentoo-r2 ~ |
| 8 |
|
| 9 |
The /boot and the tildes are returned by pushd and popd and mess up the |
| 10 |
script. |
| 11 |
|
| 12 |
There doesn't seem to be any options to turn off the echo off and shopt |
| 13 |
has nothing in it. |
