First off:
I am trying to count the number of characters in a string, but I seem to
be running into problems. I tried:
echo $STRING | wc | awk '{ print $3 }'
the only problem with this is that it drops spaces. I want to count ALL
the characters. I suppose I could just adapt some of the awk scripts that
have been flying on the newsgroups lately, but I was looking for something
clean and simple.
Secondly:
WHY -- WHY -- WHY -- WHY -- WHY -- WHY -- WHY -- WHY -- WHY -- WHY -- WHY ??
Why does the following string get pushed together??
Script:
TITLE="This is some text"
echo "$TITLE"
Output:
This is some text
How to I keep it from being pushed together??
THIRDLY:
The point of all this is to be able to center a header with pwd in it. So that
is says something like:
program 1.1 Check to see foo.bar /u/user
I need to count the spaces between bar and EOL as well as the length of the pwd
string. A while loop using expr to count takes an eternity. What could make
it faster???
Thanks in advance,
