Top Forums Shell Programming and Scripting Replace dashes positions 351-357 & 024-043 with 0 & replace " " if exis with 04 at position 381-382 Post 302708281 by lancesunny on Monday 1st of October 2012 10:40:18 AM

Hey msabhi,
awk '{if((NR>=351 && NR<=357) || (NR>=24 && NR <=43)){gsub("-","0");} else if(NR>=381 && NR<=382){gsub(" ","04");}}1' input_file
is not working.
We need to replace character - (i.e. dash) with 0 if exist between position 351 to 357. we also need to replace character - (i.e. dash) with 0 if exist between position 24 to 43. And we also need to replace two blank characters " " with 04 if exist between position 381 to 382 in same record. Each record length is 413.
I have attached input file with this thread. If we open this file with notepad++ or any other editor we can see presence of dashes at 351 to 357 & 24 to 43. for some or all records and presence " " at 81 to 382 for some records.
Thanks for you help in advance.

NAME
dpkg-awk - Utility to read a dpkg style db file SYNOPSIS
dpkg-awk [(-f|--file) filename] [(-d|--debug) ##] [(-s|--sort) list] [(-rs|--rec_sep) ??] '<fieldname>:<regex>' ... -- <out_fieldname> .. DESCRIPTION
dpkg-awk Parses a dpkg status file (or other similarly formatted file) and outputs the resulting records. It can use regex on the field values to limit the returned records, it can also be told which fields to output, and it can sort the matched fields. OPTIONS
-f filename --file filename The file to parse. The default is /var/lib/dpkg/status. -d [#] --debug [#] Each time this is specified, it increased the debug level. -s field(s) --sort field(s) A space or comma separated list of fields to sort on. -n field(s) --numeric field(s) A space or comma separated list of fields that should be interpreted as numeric in value. -rs ?? --rec_sep ?? Output this string at the end of each output paragraph. -h --help Display some help. fieldname The fields from the file, that are matched with the regex given. The fieldnames are case insensitive. out_fieldname The fields from the file, that are output for each record. If the first field listed begins with ^, then the list of fields that follows will NOT be output. BUGS
Be warned that the author has only a shallow understanding of the dpkg packaging system, so there are probably tons of bugs in this pro- gram. This program comes with no warranties. If running this program causes fire and brimstone to rain down upon the earth, you will be on your own. This program accesses the dpkg database directly in places, querying for data that cannot be gotten via dpkg. AUTHOR
