Man-Ching's ksh scripts

Interesting scripts, but I have another solution to the splitting problem using IFS.

I offer the following, which should work in vanilla bourne shell, with the using the same delimeters as Man-Ching used.

pl.sh

#!/bin/sh

line="$@"       # Save the argument list
IFS="|"         # Make '|' the field seperator

set -- $line    # reset the argument list

for column      # loop through $*
do      echo $column
done

Giving the same result 

./pl.sh `head -1 /etc/passwd | sed 's/:/|/g'`
root
x
0
1
Super-User
/
/sbin/sh

Indeed you could do the whole part in grave accents in a single sed command.

./pl.sh `sed   -e 's/:/|/g' -e 1q /etc/passwd`
root
x
0
1
Super-User
/
/sbin/sh

Which actually goes to demonstrate a bit of unix philosopy. That is, there are many ways to achieve the same end; none is necesarily the best, or more simply, there is more than one right way to do anything.

Great Dtrace article on The Register

Fired up The Register this morning to find the first article that I come across is an interview with Bryan and Adam titled Sun delivers Unix shocker with DTrace

There are also a real uses in the article from Brendon Gregg and Aeysis' Jenson.

Good interview guys!
