UNIX for Dummies Questions & Answers

Based on the output shown, I tend to agree. But, in the code Xterra was using:

Code:

sed '0,/string1/,/string2/!d' infile

the 0,/string1/ might be trying to print the 1st line of the file up to and including the first line containing string1. With the confusing description and sample input provided, I don't know whether the desired output from an input file containing:

Code:

before
string1
during
string2
after

would be:

Code:

before
string1
during

which my suggestion would produce, or:

Code:

]string1
during

which Scrutinizer's suggestion would produce.

Wouldn't sed -n '/string2/q; /string1/,$p' file be shorter and save some processing time?

Yes I considered that, but then withdrew this option, because it would mean that it would also return a result if string1 was in the file, but there was no string2, which might not be an intended outcome...

Wouldn't a non-existent string2 make the address range run till file end? And thus produce output?

Yes that is what I mean, I interpreted the OP's specification to mean that in that case there should be no output, that is why I withdrew this solution...

Thanks guys! Exactly what I needed
