Is the fixed width in bytes or in characters?
What character set are you using?
What shell are you using?
What operating system are you using?
On systems with a version of awk that conforms to the standards:
will print all lines in file that do not contain 786 characters (not counting the terminating <newline> character). If you want the count to include the <newline> character, change the 786 in that script to 785.
On some systems, the awk length() function incorrectly counts bytes instead of counting characters. If the character set you're using contains multi-byte characters (such as UTF-8), the number of bytes in a line may vary even though the number of characters is constant.

Incredibly, both BSD awk and mawk suffer from this , which is clearly a bug (mawk is supposed to be SUS v2 conformant)..
gawk and /usr/xpg4/bin/awk on Solaris functions correctly though (nawk does not, but it is not POSIX compliant so I would not expect it to).

Mac OS X picks up most of its utilities from BSD, and most of the OS X utilities do adhere to the POSIX standards requirements even in places where BSD utilities sometimes fail. The awk utility, however, fails on at least two counts:
length() should count characters; but instead it counts bytes, and
awk -v variable=value 'script' and awk -vvariable=value 'script' should be treated exactly the same, but the 1st form works and the 2nd form gives a syntax error.
At least both bash and ksh on OS X correctly count characters (not bytes) with ${#variable}.
I have one input file ABC.txt and one output DEF.txt. After the ABC is processed and created output, I want to rename ABC.txt to ABC.orig and DEF to ABC.txt. Currently when I am doing this, it does not process the input file as it cannot read and write to the same file. How can I achieve this?
