### source some config files ###

## Source the alias config file, if it exists

## add the ~/bin to the paths env var
export PATH="${HOME}/bin:${PATH}"

## uniquify paths (inplace)
export PATH=`echo $PATH | awk -F ":" '{for (i=1; i<=NF ; i++) {print $i} }' | xargs -n1 | cat -n | sort -uk2 | sort -nk1 | cut -f2- | xargs | sed -e 's/ /:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | awk -F ":" '{for (i=1; i<=NF ; i++) {print $i} }' | xargs -n1 | cat -n | sort -uk2 | sort -nk1 | cut -f2- | xargs | sed -e 's/ /:/g'`

## fix to allow for the default manpath
export MANPATH=":${MANPATH}"

## HACK: add a mount -a to manually mount partitions from the /etc/fstab file, until /etc/wsl.config starts working
#sudo mount -a
