Loses at code golf, but wins in a world where code must be read, understood, and maintained.
More seriously, Haskell won't replace shell, they've got different jobs. Haskell's real opportunities are perl and python, two omnipresent languages ill-equipped for formal math/logic but often pressed into service with the assistance bolt-on modules. This works but the syntax of calling modules for something you'd expect a builtin to do is inevitably ugly. Something with more orthogonal data structures could do a lot more with a lot less kludge. What can Haskell's data structures do?
I have a simple script that I want to run every 30 minutes but only when I execute it. I don't want it to be a crontab job.

MYVAR="$NAME"_"$NAME2".txt
where say,
NAME = one
NAME2 = two
so I want the output one_two.txt but what I am getting is,
two.txt
basically the $NAME2 is overwriting, what am I doing wrong?

egrep -A 7 -m 2 -h 'Date:|Time:' *.html
this is showing only 2 line after the context of the 2nd found match. Is this a bug in grep?

I am trying to copy 2 types of files so I can archive them. I tested with a set of commands:

Consider the following code:
grep -o -e '^STEAM_::\d+$' workfile3.tmp
A sample format of a valid string for the regexp would be:

runghc
RUNGHC(1) General Commands Manual RUNGHC(1)NAME
runghc - program to run Haskell programs without first having to compile them.
SYNOPSIS
runghc [runghc|flags] [GHC|flags] module [program|flags]...
DESCRIPTION
runghc is considered a non-interactive interpreter and part of The Glasgow Haskell Compiler. runghc is a compiler that automatically runs
its results at the end.
OPTIONS
the flags are:
-f it tells runghc which GHC to use to run the program. If it is not given then runghc will search for GHC in the directories in the
system search path. runghc -f /path/to/ghc
-- runghc will try to work out where the boundaries between [runghc flags] and [GHC flags], and [GHC flags] and module are, but you can
use a -- flag if it doesn't get it right. For example, runghc -- -fglasgow-exts Foo means runghc won't try to use glasgow-exts as
the path to GHC, but instead will pass the flag to GHC.
EXAMPLES
runghc foo
runghc -f /path/to/ghc foo
runghc -- -fglasgow-exts Foo
