I've learned that the BSD version of sed included with OS X doesn't provide an intuitive way to add newlines. I've found a few notes about it, but I don't understand yet, how to extend the examples to solve my problem.
I need to append several lines to a file and found that the lines I add do not include newline characters.
My shell script currently contains the following:
sed '/match string/ a\
newline string' ./inputfile > ./outputfile
And, I'm trying to apply the tip I found here Newlines in sed on Mac OS X
1To do that on a single line, you can use ANSI-C quoting to unescape
\n
. Additional backslashes are required before the newlines.echo $'111\n333' | sed $'/111/a\\\n222\\\n'
