Operating Systems OS X (Apple) Cat command not working as expected Post 302287651 by Daniel M. Clark on Saturday 14th of February 2009 11:42:19 PM

I found this line of code and figured that if cat wasn't going to cooperate, I'll just put my first line right into the script:

(echo '0a'; echo 'first line of text'; echo '.'; echo 'wq') | ed -s readyToProcess.txt


The resulting file was double-spaced, like I described earlier:
Quote:
first line of text
line1

line2

line3
I created a new text file called test.txt that looked like this:
Quote:
1
2
3
4
and ran:

(echo '0a'; echo 'first line of text'; echo '.'; echo 'wq') | ed -s test.txt


and it worked. So Scott, I think you're right, I think there is an issue of some sort with the datafeed file. I ran file readyToProcess.txt and it came back with readyToProcess.txt: ASCII English text, with very long lines, with CRLF line terminators

I think maybe I'm on to something?
