What is the correct syntax to have the awk parse the next line as well? The next in bold is where I think it should go, but I wanted to ask the experts since I am a beginner. The file to be parsed is attached as well. Thank you .
inputfile:
A B C D
E F G H
1 2 3 4

I want to read these and put them into a variable:
file=../inputfile
col2line1=`cat $file | awk '{print $2}'`
how do i extract row 2's E,F,G,H or row 3's 1,2,3,4???

I have files that store multiple data points for the same device "vertically" and include multiple devices. It repeats a consistant pattern of lines where for each line:
Column 1 is a common number for the entire file and all devices in that file
Column 2 is a unique device number
Column 3 is... (7 Replies)

Hello:
I am working parsing a large input file which will be broken down into multiples based on the second field in the file, in this case: STORE.
The idea is to create each file with the corresponding store number, for example: Report_$STORENUM_$DATETIMESTAMP , and obtaining the... (7 Replies)
There are 4 ways the user can input data and unfortunately the parse rules for each are slightly different. The first condition works great and the input file is attached for the second condition. Conditions 3 and 4 will follow I'm sure I will have trouble with them and need help as well. The... (9 Replies)

Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3pm)NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead.
substr($something, 1, 2) = $newvalue; # not ok
substr($something, 1, 2, $newvalue); # ok
The four-argument form of "substr()" was introduced in Perl 5.005. This policy does not report violations on code which explicitly
specifies an earlier version of Perl (e.g. "use 5.004;").
CONFIGURATION
This Policy is not configurable except for the standard options.
SEE ALSO
"substr" in perlfunc (or "perldoc -f substr").
"4th argument to substr" in perl5005delta
