Top Forums Shell Programming and Scripting How to remove part of the line from start of the line? Post 302997957 by chetanojha on Tuesday 23rd of May 2017 10:36:59 AM

Dear All,

Yes this works fine. AWK command has done the job for me. I need to know now is how can i add this output to a file.

I ran below which brings the required result in the variable.
Code:
cert1=`awk -F ":" 'NR==1 {sub("^ ", "", $2); print $2}' $temp_file`

when i am adding this output at the end of the file, it is adding ^M character in the whole file. I am using below
Code:
echo ${cert1} >> main_file.txt

One another thought, is there any way I can run java command as shown below and awk the output directly putting it into a file. Which means output of the java command should feed to the awk (which will pull blue line above) and add it to the third file?

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
