Here’s a simple way to use a persistent DIRSTACK in bash:

a script in your path called dhs saves your current DIRSTACK:

#!/bin/bash
dirs -l -p > /home/username/.drsk/pwdirs

And another one called dh to loads a dirstack from a file in ~/.drsk/, you may like to use different different dirstacks for separate projects:

#!/bin/bash
for i in `cat ~/.drsk/$1`;
do pushd $i > /dev/null 2>&1
done;
pushd +$( expr ${#DIRSTACK[@]} – 1 ) > /dev/null 2>&1
popd > /dev/null 2>&1
echo “DIRSTACK restored from ~/.drsk/$1″
dirs -v -l

and in your ~/.bashrc you can add:

source dh pwdirs

to load the default. When you adjust your working dirstack you can call `. dhs`to save it and each new terminal you open will use the same one.

I religiously update my gentoo every morning and I’ve only recently started using layman for the xeffects overlay for compiz-fusion. I had been running layman -S to sync the overlay ebuilds but I was concerned that I hadn’t emerged anything from the overlay since the initial installation. Spurred on by the beautiful demos on http://fusioncast.blogspot.com I decided to look into it.

It turns out that “live” ebuilds are always given the version 9999 so when I do emerge –update –deep world it doesn’t notice a version change and doesn’t do anything.

There’s a nice tool called eix that helps out here. Once installed and after running update-eix I ran the following to re-emerge all the live ebuilds in the xeffects overlay.

emerge -av `eix -Jc –in-overlay “/usr/portage/local/layman/xeffects” | grep 9999 | cut -d” ” -f2 | tr “\n” ” “`

I was informed on #gentoo-uk that with the new palaudis system this will be taken care of.

setxkbmap -layout gb -option lv3:ralt_switch

is equivalent to the following in xorg.conf

Option “XkbLayout” “gb”
Option “XkbOptions” “lv3:ralt_switch”

You can select variants from
/usr/share/X11/xkb/symbols/gb

I don’t know why it has taken me this long to have a look at bash. It’s great! I wrote a little script today to list the versions of various Plone packages in a release and I needed somewhere to put it:

#!/bin/bash

# spits out the details from version.txt from a toplevel directory

if [ $# -eq 0 -o $# -gt 2 ]
then
echo “Usage: $0 Directory [filename]“
echo “The directory passed to this script is where it looks for version.txt files.”
echo “The filename is for writing the results to, if it already exists then the script complains.”
echo “If no filename is provided the script writes the results to ‘the Directory name + .txt’”
fi

TLD=$1

# Try to change to the directory or give up
cd $TLD || exit

echo entered `pwd`

#Find all the version.txt files under the directory
VERS=$(find ./ -iname “version.txt” | sort)

#Get the version
for file in $VERS
do
RESULT+=”$file `cat $file`\n”
done

cd ../

#If a filename has been specified use it, otherwise call it something sensible
if [ $# -eq 2 ]
then
OUTPUT=$2
else
OUTPUT=”$1-product-versions.txt”
fi

#It the file already exists don’t overwrite anything, just print out the details
if [ -f $OUTPUT ]
then
echo -e “$OUTPUT already exists, no output has been saved:\n”
echo -e $RESULT
else
echo -e $RESULT >> $OUTPUT
echo -e “Output written to $OUTPUT”
fi

exit 0
