  • Because each of the shells has its own style of error reporting, Tables 15.3 through 15.6 illustrate the most common syntax errors, the probable cause, what the error message means, and

Here are some others, along with a quick description of what they do. >awk '{print $2,$1}' filename will print the second field, then the first. echo ab cd | awk 'NF>=2' Outputs the lines where the number of fields is 2 or more.
