how to test zipped file

It is good to test the file before unzip, doing test give you two advantages first you got a health check of zipped file and second you also got to know the list of directory and file inside zipped file without extracting.

To test the zip file use the option -t in given below format

format:

unzip -t filename.zip

Example:

root@tuxworld:/opt# ls -ld test testdir/
drwxr-xr-x 2 root root 4096 Oct 18 20:19 test
drwxrwx--- 2 joe  hr   4096 Jul 31 02:00 testdir/
root@tuxworld:/opt# zip -r mydir.zip test testdir/
  adding: test/ (stored 0%)
  adding: test/file3 (stored 0%)
  adding: test/file2 (stored 0%)
  adding: test/file4 (stored 0%)
  adding: test/file1 (stored 0%)
  adding: testdir/ (stored 0%)
  adding: testdir/testfile (stored 0%)
  adding: testdir/hgjh (stored 0%)
root@tuxworld:/opt# 
root@tuxworld:/opt# ls -l mydir.zip

root@tuxworld:/opt# unzip -t mydir.zip
