Using output of awk to run command

Question

I am brand new to shell scripting and cannot seem to figure out this seemingly simple task. I have a text file (ciphers.txt) with about 250 lines, and I would like to use the first column of each line as an argument in a command. Any help would be greatly appreciated! the command is: ``` openssl s_client -connect host:port -cipher argument ``` It works fine when I do one at a time but I do not really want to run the same command 250+ times. Here is my script so far: ``` awk '{command = "openssl s_client -connect localhost:4433 -cipher > results.txt" print $0 | command}' ciphers.txt ``` I keep getting an error so I am pretty sure I have a syntax error somewhere. Is the output of awk being appended after -cipher?

Accepted Answer

Use `system` from within awk:

```
awk '{ system("openssl s_client -connect host:port -cipher " $1) }' ciphers.txt
```
