How to Use the Head Utility   231 

Use the Head utility to view a user-defined number of lines from the start of a file. 

To run Head from the Support Tools Dashboard: 

1.  Use the System Select screen to select the system you want to work with. 

2.  From the Dashboard menu, select Common Tools > Head. 

3.  In the Arguments field, enter desired arguments, as described in the Using 

section below.  
Note: When entering arguments, the Head command is already implied. Do not 
enter it in the Arguments field. 

4.  Specify the command duration time or accept the default (60 seconds). This is 

the amount of time the command will attempt to run before terminating.  

5.  If desired, check Elevate Command Priority. This ensures the command will run 

regardless of the level of server activity. 

6.  Click the Run button. 

Head displays the first <count> lines of each of the files listed on the line. If no files 

are listed, display the first <count> lines of the standard input. 

<count> defaults to 10. 

head [-<count> | -n <count>] [-vx?] [ file1 ... ]

 

The options for Head are: 

-<count> or -n <count>

: specifies the number of lines to display.
