I couldn't find an answer for this exact problem, so I'll ask it. I'm working in Cygwin and want to reference previous commands using !n notation, e.g., if command 5 was which ls, then !5 runs the same command. The problem is when trying to do substitution, so running: !5:s/which \([a-z]\)/\1/ should just run ls, or whatever the arg...
I saw other questions dealing with the finding the n-th occurrence of a word/pattern, but I couldn't find how you would actually substitute the n-th occurrence of a pattern in vim. There's the obvious way of hard coding all the occurrences like :s/.*\(word\).*\(word\).*\(word\).*/.*\1.*\2.*newWord.*/g Is there a better way of doing ...
I'm trying to use [SymPy][1] to substitute multiple terms in an expression at the same time. I tried the [subs function][2] with a dictionary as parameter, but found out that it substitutes sequentially. In : a.subs({a:b, b:c}) Out: c The problem is the first substitution resulted in a term that can be substituted by the second substi...
Well, the title says it all. Small example: perl -e '$s="aaabbcc";$c=()=$s=~/a/g;print"$c\n$s\n"' (m//g) outputs 3 aaabbcc whereas perl -e '$s="aaabbcc";$c=()=$s=~s/a/x/g;print"$c\n$s\n"' (s///g) outputs 1 xxxbbcc I'd like to do both things at once without having to match first: substitute and know the number of substitutions. Obv...
while the method we use in Substitution control should return strings, so how is it possible to use a donut caching in web forms on a server control which should be rendered server side? for example Loginview control? ...
hi all... how would I go about taking a string ("h1", "h2", "h3, "h4") And substituting these values with numbers 1, 2, 3, 4? Correspondingly, how I would I preform the same operation but on a list instead? Thanks in advance... ...
There's a new syntax element in SP 2010's feature definitions {$ListId:Lists/ListName}. Apparently it should replace it with the GUID of the list on traget site. This solves a problem where you don't know the GUID before you create the list and have to use a feature receiver to define elements which need the GUID. Is there other such su...
Is there a way to use a variable as modifier in a substitution? my $search = 'looking'; my $replace = '"find: $1 ="'; my $modifier = 'ee'; s/$search/$replace/$modifier; I need to use an array of hashes to make bulk search-replace with different modifiers. ...
Possible Duplicate: How to use a variable in the replacement side of the Perl substitution operator? I would like to do something like $sub = "\\1"; $match = "hi(.*)"; $str = "hi1234" $res = $str; $res =~ s/$match/$sub/g I would like this to return 1234 but in this case it returns \1. I.e. I want it to be equivalent to s/$m...
I have several text files, that were once tables in a database, which is now disassembled. I'm trying to reassemble them, which will be easy, once I get them into a usable form. The first file, "keys.text" is just a list of labels, inconsistently formatted. Like: Sa 1 # Sa 2 U 328 #* It's always letter(s), [space], number(s), [spac...
Is there a way to replace text with a regex inline, rather than taking the text from a variable and storing it in a variable? I'm a perl beginner. I often find myself writing my $foo = $bar; $foo =~ s/regex/replacement/; doStuff($foo) where I'd really like to write doStuff($bar->replace(s/regex/replacement/)); or the like, rather...
My goal is to replace all instances of a trailing - to a trailing + within tag brackets. Lets assume the line to be replaced looks like this: <h> aa- aa- </h> <h> ba- ba- </h> and should afterwards look like <h> aa+ aa+ </h> <h> ba+ ba+ </h> First I tried this expression: s/<h>(.*?)-(.*?)<\/h>/<h>$1+$2<\/h>/g; which yielded th...
My previous post got the tags partially stripped, so here it is again: My goal is to replace all instances of a trailing - to a trailing + within tag brackets.

Really would appreciate help on this. I am using sed to create a CSV file. Essentially multiple html files are all merged to a single html file and sed is then used to remove all the junk pictures etc to get to the raw columnar data.
