Skripta za linkat datoteke in mape iz ene lokacije na drugo.

t3ch

Skripta ki linka datoteke iz lokacije na lokacijo. Meni je uporabna pri installiranju sourcev na druge lokacije torej z drugacnim --prefix om. Npr.: Ti installas ffmpeg:

# mkdir /home/user/ffmpeg
# ./configure --prefix=/home/user/ffmpeg
# make
# make install
# cd /home/user/ffmpeg
# ./skripta --link $(pwd)/bin /usr/bin

To bo linkalo vse binarne datoteke iz lokaciji /home/user/ffmpeg/bin na lokacijo /usr/bin/...
( to ponovis z direktoriji /lib, /share, /sbin, itd... )

Lahko tudi unlinkas z --unlink argumentom. Če se radi igrate s kompajlanjem sourcov bo vam mogoče prisla prav.
