Re^2: how to convert new line to ","

The shell command-line equivalent:

cat data.txt | perl -00pe 's/\\n/,/g'
[download]
Update: Oops! My mistake. I needed to add "-l" argument and also be careful of how the shell interprets '\n':

    cat data.txt | perl -l -00pe 's/\n/,/g'
[download]

Did you actually test that? When I tried it did replace newlines with commas, but also the double newlines that bh_perl doesn't want to have replaced.	[reply]

The working line would be `perl -00pe 'chomp; s/\n/,/g; s/$/\n/' data.txt` [download] and, yes, I tested it :-) the `chomp` yanks the last `\n\n`, so you must put one again at the end b4 printing. []s, HTH, Massa (κς,πμ,πλ)	[reply] [d/l] [select]

We can get around chomping with the "-l" argument.	[reply]
