OSX Snow Leopard has a command line
Today I needed to unzip a MASSIVE (10GB) zip file (for Adobe LiveCycle - but that’s another story)… and got this response:
unzip LiveCycleES2.5-0.0.5.zip Archive: LiveCycleES2.5-0.0.5.zip skipping: LiveCycleES2.5-0.0.5/LiveCycleES2.5.x86_64-0.0.5.vmdk need PK compat. v4.5 (can do v2.1) creating: LiveCycleES2.5-0.0.5/ inflating: LiveCycleES2.5-0.0.5/LiveCycleES2.5.x86_64-0.0.5.vmx
So what’s PK compat. v4.5 ? The standard zip libraries don’t let you unzip really big files. The PKZip libraries have evolved with myriad different versions and capabilities - including (in 4.5) the addition of Zip64 - with support for huge (>4.5 GB) files.
To get it to work, we need p7zip the Linux/Unix port of the 7-zip libraries.
I use homebrew - and you should too.
brew install p7zip
then use the 7z utility (with a magic ‘x’ for extract like so:
7z x LiveCycleES2.5-0.0.5.zip
…and we’re cookin with gas.
