The first blank after the second quote ends the awk script. A quick search for how to correctly escape single quotes in the shell should help you resolve the issue.

Out Of Trouble by William Shotts, Jr. Now that our scripts are getting a little more complicated, I want to point out some common mistakes that you might run into. To do this, create the following script called trouble.bash. Be sure to enter it http://linuxcommand.org/wss0100.php exactly as written. #!/bin/bash number=1 if [ $number = "1" ]; then echo "Number equals 1" else echo "Number does not equal 1" fi When you run this script, it should output the line "Number equals 1" because, well, https://www.gnu.org/s/gawk/manual/gawk.html number equals 1. If you don't get the expected output, check your typing; you made a mistake. Empty variables Edit the script to change line 3 from: number=1 to: number= and run the script again. This time you syntax error should get the following: [me@linuxbox me]$ ./trouble.bash /trouble.bash: [: =: unary operator expected. Number does not equal 1 As you can see, bash displayed an error message when we ran the script. You probably think that by removing the "1" on line 3 it created a syntax error on line 3, but it didn't. Let's look at the error message again: ./trouble.bash: [: =: unary operator expected We can see that ./trouble.bash is reporting the error awk syntax error and the error has to do with "[". Remember that "[" is an abbreviation for the test shell builtin. From this we can determine that the error is occurring on line 5 not line 3. First, let me say there is nothing wrong with line 3. number= is perfectly good syntax. You will sometimes want to set a variable's value to nothing. You can confirm the validity of this by trying it on the command line: [me@linuxbox me]$ number= [me@linuxbox me]$ See, no error message. So what's wrong with line 5? It worked before. To understand this error, we have to see what the shell sees. Remember that the shell spends a lot of its life substituting text. In line 5, the shell substitutes the value of number where it sees $number. In our first try (when number=1), the shell substituted 1 for $number like so: if [ 1 = "1" ]; then However, when we set number to nothing (number=), the shell saw this after the substitution: if [ = "1" ]; then which is an error. It also explains the rest of the error message we received. The "=" is a binary operator; that is, it expects two items to operate upon - one on each side. What the shell was trying to tell us was that there was only one item and there should hav
