Shell/Perl script to convert to Capitalize case
I need a shell script which will convert the given string within a <title> tag to Capitalize case.




E.g "<title>hi man: check this out</title>"


to "<title>Hi Man: Check This Out</title>"

You can do this in Bash, although I wouldn't Smilie

Code:
$ shopt -s compat31
$ string="<title>This is a test</title>"
$ [[ "$string" =~ "<title>(.*)</title>" ]] && echo ${BASH_REMATCH[1]} | tr "[:lower:]" "[:upper:]"
THIS IS A TEST

Ack! You want the first letter of every word capitalized? Okay, a bit trickier than I first thought. Here's the basic case:
Code:
perl -e -p 's/(<title[^>]*>)([^<]*)(<\/title)>/$1 . ucfirst($2) . $3/se'

Here's one way so every word is capitalized. There are always Other Ways too:
Code:
perl -p -e 'if(/(<title[^>]*>)([^<]*)(<\/title>)/) { ' \
          -e '  $lhs= $PREMATCH . $1; $rhs = $POSTMATCH . $3; '\
          -e '  $title = join(" ",map(ucfirst($_),split(" ",$2))); '\
          -e '  $_ = $lhs . $title . $rhs;'\
          -e '}'

The complex line: (1) splits the title string into words (delimited by spaces) and (2) makes every word (via map) capitalized (with ucfirst), and (3) recombines the strings with join. The the entire line is reconstituted.

This won't work if <title> is spread across multiple lines. For that, you should use one of the HTML parsers.

Um, you have to provide a filename or redirect the file into it. Also, I had forgotten an apostrophe. I corrected the post. Try it now.

Or:

Code:
perl -pe's|
    (?<=<title>)
    (.*?)
    (?=</title>)
    |($x=$1)=~s/\b(\w)/\u$1/g;$x
    |gxe'  infile
