Top Forums Shell Programming and Scripting How to replace multiple "&nbsp;" entry with in <td> tag into single entry using sed? Post 302989195 by Corona688 on Monday 9th of January 2017 04:16:00 PM

-e is redundant here. If your SED supports extended regexps:

Code:
$ echo "&nbsp; &nbsp; &nbsp; a &nbsp; &nbsp; &nbsp;" | sed -r 's/(&nbsp; *)+/\&nbsp;/g'
&nbsp;a &nbsp;

$

The ( ) brackets group a whole section, after which is a + for "one or more repeats of this expression".

The & has to be escaped in the output expression as \&, otherwise & has the special meaning "the entire matched expression" which would end up adding MORE &nbsp;

Question though: If specific numbers of non-breaking spaces aren't meant to be there, are any non-breaking spaces meant to be there? Why not replace them entirely with non-breaking spaces?

tracker-tag

tracker-tag(1)							   User Commands						    tracker-tag(1)

NAME

       tracker-tag - Add, remove and list tags.

SYNOPSIS

       tracker-tag [OPTION...] FILE [FILE...]
       tracker-tag [OPTION...] -t [[TAG] [TAG] ...]

DESCRIPTION

       tracker-tag allows the caller add tags, remove tags and list tags by URN or to list all tags and the files associated with them.

       The FILE argument can be either a local path or a URI. It also does not have to be an absolute path.

OPTIONS

       -?, --help
	      Show summary of options.

       -l, --limit=N
	      Limit search to N results. The default is 512.

       -o, --offset=N
	      Offset the search results by N. For example, start at item number 10 in the results. The default is 0.

       -r, --or-operator
	      Use OR for search terms instead of AND (the default)

       -t, --list
	      List  all tags. Results include the number of files associated with that tag and the tag's unique identifier. You can show the files
	      associated with each tag by using --show-files.

	      The TAG arguments are optional. If no TAG argument is specified, all tags are listed. If one or more TAGs are  given,  all  matching
	      tags are listed. For example, this will match any tags named either foo, bar or baz:

	      $ tracker-tag -t foo bar baz

       -s, --show-files
	      Show the files associated with each tag. This option is ONLY available WITH the --list option.

       -a, --add=TAG
	      Add  a tag with the name TAG. If no FILE arguments are specified, the tag is simply created (if it didn'talready exist) and no files
	      are associated with it. Multiple FILE arguments can be specified.

       -d, --delete=TAG
	      Delete a tag with the name TAG. If no FILE arguments are specified, the tag is deleted for ALL files. If FILE arguments  are  speci-
	      fied, only those files have the TAG deleted.

       -e, --description=STRING
	      This option ONLY applies when using --add and provides a description to go with the tag label according to STRING.

       -V, --version
	      Print version.
