The test Command
 
−
 
 
−
= BASH has a built-in test command (similar to /bin/test) which can perform basic string and integer comparisons using these operators (results are returned as an exit code):
 
−
= return 0 or 1, where 0 is true, 1 is false
 
−
 
 
−
Operator Comparision type Comparison Example
 
−
-eq Integer Equal $x -eq 4
 
−
-ne Integer Not equal $x -ne 4
 
−
-gt Integer Greater than $x -gt 0
 
−
-lt Integer Less than $x -lt 1000
 
−
-ge Integer Greater/equal $x -ge $y
 
−
= String Equal "$x" = "Y"
 
−
!= String Not equal "$x" != "NEVER"
 
−
 
 
−
Unary File Tests
 
−
Operator Test Example
 
−
-e File exists [ -e /etc/passwd ]
 
−
-r File is readable [ -r /etc/hosts ]
 
−
-w File is writable [ -w /tmp ]
 
−
-x File is executable [ -x /usr/bin/ls ]
 
−
-f File is a regular file [ -f /dev/tty ]
 
−
-d File is a directory [ -d /dev/tty ]

RPM file names normally have the following format:
 
−
<name>-<version>-<release>.<arch>.rpm
 
−
 
 
−
== Query / Verify commands
 
−
  1. Getting detailed information:
 
−
      $ rpm -qi wget
 
−
  2. Determining which package installed /usr/bin/wget:
 
−
      $ rpm -qf /usr/bin/wget
 
−
  3. Showing all the files installed by the package wget:
 
−
      $ rpm -ql wget
 
−
  4. Viewing the documentation files for the command wget:
 
−
      $ rpm -qd wget
 
−
  5. Listing all files included in the not yet installed package wget by entering the following:
 
−
      $ rpm -qpl /mnt/iso/suse/i586/wget-1.10.2-78.i586.rpm
 
−
  6. Listing all files included in the installed package wget:
 
−
      $ rpm -ql wget
 
−
  7. Verifying that a package is no longer installed by entering:
 
−
      $ rpm -qa | grep wget
 
−
  8. Seeing what has changed in the files on your hard drive since the wget RPM was originally installed by entering the following:
 
−
      $ rpm -V wget
 
−
  9. Checking package to ensure its integrity and origin: (NOTE: gpg or pgp software must be installed on your system before you use this command)
 
−
      $ rpm -K /mnt/iso/suse/i586/wget-1.10.2-78.i586.rpm
 
−
 
 
−
== Install / Uninstall / Upgrade commands
 
−
  1. Installing the package wget:
 
−
      $ rpm -ivh /mnt/iso/suse/i586/wget-1.10.2-78.i586.rpm
 
−
  2. Uninstalling the package wget:
 
−
      $ rpm -e wget
 
−
  3. Upgrading the package wget: (NOTE: if the package is not installed it will install it for You, like option "-ivh")
 
−
      $ rpm -Uvh /mnt/iso/suse/i586/wget-1.10.2-78.i586.rpm
 
−
  4. Extracting RPM file using rpm2cpio and cpio command: (NOTE: RPM content will be extracted the current directory)
 
−
      $ rpm2cpio wget-1.10.2-78.i586.rpm | cpio -idmv
