How does this works?
What does sed -e 's/<[^>]*>//g' actually do?
What if I wanted to get content of a line with pattern something like this, [tag2]content[/tag2]?
thanks..
The first sentence removes all the tags so the content remains.
Code:
$ echo "<tag1>content</tag1>" | sed 's/<[^>]*>//g'
content

To do the same with [] you could do this:
Code:
$ echo "[tag2]content[/tag1]" | sed 's/\[[^]]*\]//g'
content

SYNOPSIS
array imap_listscan (resource $imap_stream, string $ref, string $pattern, string $content) DESCRIPTION

o $ imap_stream -An IMAP stream returned by imap_open(3). o $ref -$ref should normally be just the server specification as described in imap_open(3) o $pattern -Specifies where in the mailbox hierarchy to start searching.There are two special characters you can pass as part of the $pat- tern: ' *' and ' %'. ' *' means to return all mailboxes. If you pass $pattern as ' *', you will get a list of the entire mailbox hierarchy. ' %' means to return the current level only. ' %' as the $pattern parameter will return only the top level mailboxes; ' ~/mail/%' on UW_IMAPD will return every mailbox in the ~/mail directory, but none in subfolders of that directory. o $content - The searched string RETURN VALUES
