Apr 20 06:50:59 <brolin_empey> sicelo: If you only need to replace a literal string in a shell pipeline then you can use tr instead of a substitute commnand in sed.
Apr 20 06:51:40 <brolin_empey> s/commnand/command/
Apr 20 06:53:10 <luke-jr> tr doesn't replace strings
Apr 20 06:53:23 <luke-jr> only characters
Apr 20 07:25:02 <sixwheeledbeast> The example was a single char as far as I can tell. Also maybe either tr or sed's delete would be more ideal over replace for blank?
Apr 20 07:41:40 <sixwheeledbeast> I have also fell into replace for blank, where sed '/foo/d;/bar/d' would be more efficient 
Apr 20 07:59:01 <DocScrutinizer05> sth in grep urgently needs optimization:  https://pastebin.com/7y1Kx3W6
Apr 20 09:34:16 <Maxdamantus> but the `d` command discards the current line.
Apr 20 09:34:25 <Maxdamantus> rather than just removing a character.
Apr 20 09:36:52 <Maxdamantus> DocScrutinizer05: try LC_ALL=C
Apr 20 09:40:20 <Maxdamantus> alternatively, you could just use sed, which doesn't seem to do the unnecessary unicode processing (which I think is basically wrong anyway)
Apr 20 10:35:59 <sixwheeledbeast> I suppose so, depends on the situation as yu say
Apr 20 19:04:08 <DocScrutinizer05> on topic:   alias man=':(){ [ "sed" == "$1" ]||{ /usr/bin/man $*;return; }; less -f <(/usr/bin/man sed) <(wget http://sed.sourceforge.net/sed1line.txt -q -O -); };:'
Apr 20 19:04:18 <DocScrutinizer05> mad useful
Apr 20 19:09:51 <DocScrutinizer05> sorry, replace $* by "$@"
Apr 20 19:12:56 <DocScrutinizer05> anyway, don't miss http://sed.sourceforge.net/sed1line.txt
Apr 20 19:13:53 <DocScrutinizer05> you can bin ca 50% of other tools like tr, head, tail, whatnot.  sed does it all
Apr 20 22:00:07 <Maxdamantus> If you run that alias, it overrides the : command.
Apr 20 22:02:08 <Maxdamantus> in general, alias is a pretty ugly way of overriding commands though .. you can just write functions instead, and avoid the funny escaping stuff.
Apr 20 22:03:32 <Maxdamantus> man(){ [ "sed" == "$1" ]||{ /usr/bin/man "$@";return; }; less -f <(/usr/bin/man sed) <(wget http://sed.sourceforge.net/sed1line.txt -q -O -); }
