There are several command-line utilities to review the contents of a file in Enterprise Linux. These include:

1. more

   • The most traditional pager in Linux. The user presses “Space” to move through a file using more. Standard search functionality (/) works similar to how it does in man pages or vim
   • Typical Usage:
     • more myFile.txt
     • cat myFile.txt | more - less efficient but commonly used

2. less

   • Built to address the shortcomings of more, less has additional features such as scrolling via arrow keys (as well as “Space”) and the same search functionality (/). Generally preferred by most users.
   • Typical Usage:
     • less myFile.txt
     • cat myFile.txt | less - less efficient but common used

3. view

   • A “read-only” mode for the vim editor.
   • Has all the same functionality as vi or vim - users can search the document, move the cursor to the beginning/end of lines or the document itself.
   • User can even modify the document, but cannot save it without the ! flag (and appropriate file permissions of course)
   • Typical Usage:
     • view myFile.txt

4. cat

   • Most basic way to view a file in CLI
   • Not really a file pager, but used to view short files effectively. Returns the entire contents of the file to the terminal - so less useful for larger files.
   • Often used in conjunction with pipes - helps to get the entire contents of a file passed to the next command
   • Typical usage:
     • cat myFile.txt
     • cat myFile.txt | grep -v 'notLinesWithThisText'
