Hello,
Say I have a file with plain text as shown below. Some columns may have multiple words (like "DESC 1", "DESC 1 2", "DESC 1 2 3"). Let's say the file below has 4 columns: 1st(AA), 2nd(BB), 3rd(DESC 1, ...), 4th(CC 1, ...).

I need a script (perl or awk..anything is fine) to join 3 files based on three key columns. The no of non-key columns can vary in each file. The columns are delimited by semicolon.
For example,
File1
Dim1;Dim2;Dim3;Fact1;Fact2;Fact3;Fact4;Fact5
---- data delimited by semicolon ---

Hello
If you wanted to sort a .csv file that was filled with lines like this:
<Ticker>,<Date as YYYYMMDD>,<Time as H:M:S>,<Volume>,<Corr>
(H : , M, S: )
by date, does anybody know of a better solution than to turn the 3rd and 4th colons of every line into commas, sorting on four keys,... (20 Replies)
Can you guys pls take a look at this.
I need to sort this list of numbers as follows:
2nd col first, then 1st col, then 3rd col, all in reverse (highest to lowest).
I'm doing this:
sort -k 2,2nr -k 1,1nr -k 3,3gr
but, as you see, the 3rd col does not get sorted properly.
Any idea... (0 Replies)

Hi,
I'm not a regular coder but some times I write some basic perl script, hence Perl is bit difficult for me :).
I'm merging two files a.txt and b.txt into c.txt:

x001;frvt65;sec;239

Hello,
I am writing a script which expects as its input a hash with student names as the keys and marks as the values. The script then returns array of average marks for student scored 60-70, 70-80, and over 90.
Output expected
50-70 1
70-90 3
over 90 0

dpkg-awk
DPKG-AWK(1) General Commands Manual DPKG-AWK(1)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.
