Speed up builds and scripts, remove duplicate entries in $PATH. Users scripts are oftern bad: PATH=/apath:$PATH type of thing cause diplicate.

Thanks to the authors of:

awk '!x[$0]++' <file>

and the author of:

joinargs() { (local IFS="$1"; shift && echo "$*") }

and others, we can have a fast Linux or android.

IMPORTANT if you find a priority order problem in PATH you can push a path directory to the front without duplication as follows:

PATH=/bin:$PATH

then ...

Check duplication with:

echo $PATH|tr : '\n'|sort|uniq -d

Finally do a very neat line by line list of $PATH:

echo "${PATH//:/$'\n'}

The speed up is very noticeable for android, and builds on Linux Ubantu are much faster with make and scripts.

I will update the command on request. Timothy from SONY

Define dettaching commands in bashrc

Define commands that you always invoke with an appended '&disown'. In the example:

gvim foo.txt

will open gvim dettached from the current terminal.
