emulating cat in sed with q option
Hi,

I am aware that the below are the equivalent in sed for cat command.
Code:
sed ':'
sed -n 'p'

Is there any way to emulate the same using "q" option in sed?

Thanks

Assuming that there are less than 100,000 lines in your file:

Code:
sed '100000q' filename.txt

Yes. But the thing is we don't know the number of lines in the file. It may be dynamic.
Is there any one liner available using "q" in this case?
We can do it after finding wc -l , then using "q" in sed.
But is there any other smarter way?
Thanks

The smart way is to not use 'sed'.

Any real world reason for this question?

Thanks

Try this:-
Code:
alias sed=cat

Of course this means you can't use anything else in sed but then if you want to use the wrong tool to replace cat, then this must be suitable.......


As it is Christmas
Code:
cat "food in tins"
