redirects error output to "no where"
it is a common trick in programming unix

Why I used...
wanted to do a number comparison on a field
if number comparison was with a number, could do it
if numb comp was with text, it would error; so I "skip over" the error

Not very elegant, but gets the job done. In reality, I should have checked for $0 looking at return codes, blah blah....

Now that you have working code, you can make it nice and pretty!

The default width is 72. concatenates the arguments. If none are given, formats text from the standard input. Blank lines are preserved in the output, as is the spacing between words. does not fill lines beginning with a period for compatibility with Nor does it fill lines starting with Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used). can also be used as an in-line text filter for the command: reformats the text between the cursor location and the end of the paragraph. Options recognizes the following options: Crown margin mode. Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that of the second line. This is useful for tagged paragraphs. Split lines only. Do not join short lines to form longer ones. This prevents sample lines of code, and other such "formatted" text, from being unduly combined. Fill output lines to up to width columns. WARNINGS
The width option is acceptable for BSD compatibility, but it may go away in future releases. SEE ALSO
