sed and regular expressions
Hi,
There's a bug using JavaDoc that generates an error if a tag <a...> is found in a javadoc comment, which is not a HTML reference. For example this error is produced with generics. I want to insert an space between "<" and "a". Expression is able to find where this happens using
find and
grep:
Quote:
find . -iname "*.java" | xargs grep -E "[:space:]*\*+.*<[aA][^[:space:]].*"
But i'm not able to generate the output expression. I don't know how keep the first part of expressión (until "<") add an space, and concatenate with the second part. For example, from:
Quote:
* List<AlmacenOrdenacion>). Debería pasar...
To:
Quote:
* List< AlmacenOrdenacion>). Debería pasar...
Just and a space between "List<" and "Almacen".
I'm trying to get all lines using above
find command. Use
cut -d "<" to separate parts, add an space and finally use sed to substitute in file. But I guess there must be an easy way using sed with regular expressions.
Anyone can help me?
Thanks.

Ok, so I get that:

...will print every line from START to END inclusive, but I don't want to see START or END. Apart from the obious:
sed -n '/START/,/END/p' file | grep -v "START" | grep -v "END"

GREP(1) General Commands Manual GREP(1)
NAME
grep - search a file for lines containing a given pattern
SYNOPSIS
grep [-elnsv] pattern [file] ...
OPTIONS
-e -e pattern is the same as pattern
-c Print a count of lines matched
-i Ignore case
-l Print file names, no lines
-n Print line numbers
-s Status only, no printed output
-v Select lines that do not match
EXAMPLES
grep mouse file # Find lines in file containing mouse
grep [0-9] file # Print lines containing a digit
DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions
accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1
occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a
match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is
returned.
