I am trying sed s/\w/\u/g but it doesn't do anything. I think because it doesn't recognize the \u ?
GNU sed version 4.1.2

sed 's/\w/\u&/' \u must apply to something; by itself it does nothing; in this case & means "whatever matched the search pattern". g is to be omitted if you want just the first letter; if you include g it will make uppercase all letters.

sed "s/.*/\L&/g" | sed "s/\w/\u&/"because i first want to lowercase everythingUFC Insider– UFC Insider2016-11-27 20:33:49 +00:00Commented Nov 27, 2016 at 20:33 -
sed -e 's/.*/\L&/' -e 's/\w/\u&/'absolutely works, I have tested it. Can you tryls -l | sed -e 's/.*/\L&/' -e 's/\w/\u&/'as a quick test?AlexP– AlexP2016-11-27 20:37:02 +00:00Commented Nov 27, 2016 at 20:37 - it just trims the first letter for some reason... weirdUFC Insider– UFC Insider2016-11-27 20:51:44 +00:00Commented Nov 27, 2016 at 20:51
- 1This requires GNU sed. It won't work on standard UNIX / BSD sed.dhchdhd– dhchdhd2017-04-27 05:41:43 +00:00Commented Apr 27, 2017 at 5:41
