  1. # unzip -t var-log.zip
  2.  
  3.      Archive:  var-log.zip
  4.     testing: var/log/acpid            OK
  5.     testing: var/log/anaconda.log     OK
  6.     testing: var/log/anaconda.syslog   OK
  7.  
  8. skip...
  9.  
  10.     testing: var/log/wtmp             OK
  11.     testing: var/log/wtmp.1           OK
  12.     testing: var/log/Xorg.0.log       OK
