linker4osx - How to start multiple instances of an application on Mac OSX

This script makes link to your applications, and you can start it in multiple instances.

 #linker4osx by PeTIK Team  ... draft only
 #!/bin/bash  
 echo '#!/bin/bash' > $2/$1  
 echo '/Applications/'$1'.app/Contents/MacOS/'$1' &' >> $2/$1   
 echo echo $1 started... >> $2/$1  
 chmod +x $2/$1  
   
 usage:  
 sudo ./linker4osx APPLICATION_NAME_IN_YOUR_APP_FOLDER DESTINATION_FOLDER_TO_LINK  
   
 usage example:  
 sudo ./linker4osx VLC /usr/bin  
   
   

and you can start a lot of VLC from Terminal (too...) :)

xrandr - change screen resolution from terminal

Csak amíg feledésbe nem merül...

Nagyon jó cucc, a display-eket lehet vele konfigolni.

pl.:

 xrandr --output LVDS --off
  
 xrandr --output LVDS --auto 
  
 xrandr --output VGA --mode 1680x1050 --rate 80
  

remove CR from windows text file

 (ba)sh:$ dos2unix file.txt  

Több videó (elejének) vágása 1xre

 for i in `ls *.avi`;
  
 do echo Alakítom: $i;
  
 #ffmpeg -i $i -ss 00:00:44 vagott${i:0} <---lassú
  
 mencoder -ss 00:00:44 -oac copy -ovc copy "$i" -o vagott${i:0}
  
 done  

vége levágása:

 mencoder -endpos hh:mm:ss -ovc copy -oac copy in.avi -o out.avi  

Bash: több kép átméretezése egyszerre

 for i in `ls pic*.jpg`; do echo $i; convert $i -resize 1024x768 -quality 75 m${i:1}; done
