grep to generate a file
Hi

I need help with the following problem.

I need to use grep to generate the file text1.txt which is identical to text.txt but contains no blank lines.

I am a complete novice at grep so any help will be great.

Thanks in advance.

Normally I don't answer these threads cause we have so much great talent on the site, but I feel like everyone else is having all the fun Smilie

Code:
grep -v "^ " text.txt > text1.txt

(ok, this is my last one ...)

Can also be done like this:
Code:
grep -v ^$ text.txt > text1.txt

depending on your definition of 'blank lines':
Code:
sed '/^$/d' myFile
nawk 'NF' myFile
grep -v '^$'  myFile

Much better than my incomplete suggestion. Smilie

this will generate lines NOT starting with a 'space' - don't think it's the OPs definition of 'blank lines' Smilie
