Re: update-profiles.sh

[Wojtek Kosior]

Hi Gottfried,

I see several problems with `update-profiles.sh`.
- You wrote `GUIX_PROFILES=home/gfp/Projekte`, without leading slash.
  This makes the shell treat this path as a relative one. You need to
  use either `/home/gfp/Projekte` or just '$HOME/Projekte'.
- This script assumes manifests to be stored in a completely different
  place than they really are in your case.
- There's no need to `unset` the loop variables at every iteration. At
  least as long as this script is executed and not sourced. I'm
  mentioning this although a few extraneous `unset`s are not going to
  cause problems. Don't worry too much about this.

I edited the script. Try with this version

```
#!/bin/sh

GUIX_PROFILES=$HOME/Projekte

for dir in $GUIX_PROFILES/*
do
     name=$(basename "$dir" | tr '[:upper:]' '[:lower:]')
     manifest="$dir"/$name.scm
     profile=$dir/$name
     if [ -r $manifest ]
     then
         guix package --manifest="$manifest" --profile="$profile"
     fi
done
```
