Full Discussion: Using sed to execute multiple commands
Top Forums Shell Programming and Scripting Using sed to execute multiple commands Post 302833241 by DGPickett on Tuesday 16th of July 2013 02:52:12 PM

Let's open it up for ease of maintenance. I never used -r for extended regex, as usually my sed is not GNU! The third substitute does not need it, as [] is implicitly and or.
Code:
sed -rn '
  /DIP-10219/{
    s/^.*[^,](cn=.*com).*$/\1/
    s/hbo/&-ns/g
    s/[(]|[)]/\\&/g
    p
   }
 ' in_file >out_file

Removing duplicates can be done by sed only if the file is sorted, but it can be done by 'sort -u' or 'uniq', if you are talking about whole line duplicates or well defined key field duplicates. In some situations, people need to remove later or earlier lines with the same key fields that are not entirely duplicate lines. One behaviour of 'sort -u' that is very useful is that all later lines for the key are deleted; the first survives. Sometimes we sort the file in reverse order if the last for a key is desired. To detect duplicates on the fly, you need a tool that can store past lines or keys and look up each line, like awk, ksh or bash.

msguniq

MSGUNIQ(1)								GNU								MSGUNIQ(1)

NAME

       msguniq - unify duplicate translations in message catalog

SYNOPSIS

       msguniq [OPTION] [INPUTFILE]

DESCRIPTION

       Unifies duplicate translations in a translation catalog.  Finds duplicate translations of the same message ID.  Such duplicates are invalid
       input for other programs like msgfmt, msgmerge or msgcat.  By default, duplicates are merged together.  When using the  --repeated  option,
       only  duplicates  are  output,  and  all  other	messages are discarded.  Comments and extracted comments will be cumulated, except that if
       --use-first is specified, they will be taken from the first translation.  File positions  will  be  cumulated.	When  using  the  --unique
       option, duplicates are discarded.

       Mandatory arguments to long options are mandatory for short options too.

   Input file location:
       INPUTFILE
	      input PO file

       -D, --directory=DIRECTORY
	      add DIRECTORY to list for input files search

       If no input file is given or if it is -, standard input is read.

   Output file location:
       -o, --output-file=FILE
	      write output to specified file

       The results are written to standard output if no output file is specified or if it is -.

   Message selection:
       -d, --repeated
	      print only duplicates

       -u, --unique
	      print only unique messages, discard duplicates

   Input file syntax:
       -P, --properties-input
	      input file is in Java .properties syntax

       --stringtable-input
	      input file is in NeXTstep/GNUstep .strings syntax

   Output details:
       -t, --to-code=NAME
	      encoding for output

       --use-first
	      use first available translation for each message, don't merge several translations

       -e, --no-escape
	      do not use C escapes in output (default)

       -E, --escape
	      use C escapes in output, no extended chars

       --force-po
	      write PO file even if empty

       -i, --indent
	      write the .po file using indented style

       --no-location
	      do not write '#: filename:line' lines

       -p, --properties-output
	      write out a Java .properties file

       --stringtable-output

       -w, --width=NUMBER
	      set output page width

       --no-wrap
	      do not break long message lines, longer than the output page width, into several lines

       -s, --sort-output
	      generate sorted output

       -F, --sort-by-file
	      sort output by file location

   Informative output:
       -h, --help
