Suppose it was a Q separating the xxx and the iii. You would just type "grep "xxxQiii" wouldn't you? The answer to your question is the same, except that instead of Q, you need to type the tab key. Tab is just another character.

3. UNIX for Dummies Questions & Answers
I try to remove empty lines from file and use next:
> cat fl.dat|grep -v '^*$'
or
cat fl.dat|sed '/^*$/d'
'grep' does not removes lines with tabs, 'sed' - lines with <tab> and with <spc>
Why it could be?
Is there any option/env-var should I check?
Thank you

sort::key::multi
Sort::Key::Multi(3pm) User Contributed Perl Documentation Sort::Key::Multi(3pm)
NAME
Sort::Key::Multi - simple multikey sorts
SYNOPSIS
use Sort::Key::Multi qw(sikeysort);
my @data = qw(foo0 foo1 bar34 bar0 bar34 bar33 doz4)
my @sisorted = sikeysort { /(w+)(d+)/} @data;
DESCRIPTION
Sort::Key::Multi creates multikey sorting subroutines and exports them to the caller package.
The names of the sorters are of the form "xxxkeysort" or "xxxkeysort_inplace", where "xxx" determines the number and types of the keys as
follows:
+ "i" indicates an integer key, "u" indicates an unsigned integer key, "n" indicates a numeric key, "s" indicates a string key and "l"
indicates a string key that obeys locale order configuration.
+ Type characters can be prefixed by "r" to indicate reverse order.
+ A number following a type character indicates that the key type has to be repeated as many times (for instance "i3" is equivalent to
"iii" and "rs2" is equivalent to "rsrs").
+ Underscores ("_") can be freely used between type indicators.
For instace:
use Key::Sort::Multi qw(iirskeysort
i2rskeysort
i_i_rs__keysort
i2rs_keysort);
exports to the caller package fourth identical sorting functions that take two integer keys that are sorted in ascending order and one
string key that is sorted in descending order.
The generated sorters take as first argument a subroutine that is used to extract the keys from the values which are passed inside $_, for
example:
my @data = qw(1.3.foo 1.3.bar 2.3.bar 1.4.bar 1.7.foo);
my @s = i2rs_keysort { split /./, $_ } @data;

For a more general multikey sorter generator see Sort::Key::Maker.
