Actually I want to express the backticks in command and attach it to a file.
For example:
I got a list of file end at .txt. I want all of them do the same command like
awk '{print $_"\t"}' and attached it to a output .sh file.

This is the command I type:
ls *.txt | awk '{print $1, " | awk \' \{ print $_ \" \\t \" \} \' "}' > txt.sh

My desired output is when I type the command "more txt.sh "
The desired output is like this:
sample1.txt | awk '{print $_"\t"}'
sample2.txt | awk '{print $_"\t"}'
sample3.txt | awk '{print $_"\t"}'
sample4.txt | awk '{print $_"\t"}'

I got the problem when trying to show out the ' (backtick) at the txt.sh file.
I used the \' to show out the ' (backticks).
Is't because I use wrong?
Thanks a lot for your advice and suggestion.

Thanks for your suggestion.
Do you have any idea to help me show out the ' (backticks).
Thus I can get the desired output result.
