Comparing string lengths

Your title is incorrect. You do not want to compare integers, you want to compare string lengths.

Code:
while read n
do
  [ ${#n} -ge 5 ] && printf "%s\n" "$n"
done < FILE

For a large file, it will be faster with awk, sed or even grep:

Code:
awk 'length >= 5' FILE

awk '/...../' FILE

sed -n '/...../p' FILE

grep '.....' FILE

I have two arrays I need to compare against a third, looking for matches, not differences. I think I'm going to have to convert the arrays to files and grep them, but I'm not too sure if there's a tool to enable me to matches specifically, instead of differences. Thanks in advance! Karl (9 Replies)

apple_dump

APPLE_DUMP(1)							   Netatalk 2.2 						     APPLE_DUMP(1)

NAME

       apple_dump - Dump AppleSingle/AppleDouble format file

SYNOPSIS

       apple_dump [-a] FILE | DIR
							  apple_dump -f FILE
							  apple_dump -d FILE
							  apple_dump -h | -help | --help
							  apple_dump -v | -version | --version

DESCRIPTION

       apple_dump dump AppleSingle/AppleDouble format file.

OPTIONS

       -a FILE|DIR
	   This is default. Dump a AppleSingle/AppleDouble file for FILE or DIR automatically. Extrapolate FinderInfo type from absolute path. If
	   FILE is not AppleSingle/AppleDouble format, look for .AppleDouble/FILE and ._FILE. If DIR, look for DIR/.AppleDouble/.Parent and ._DIR.

       -f FILE
	   Dump FILE. Assume FinderInfo to be FileInfo.

       -d FILE
	   Dump FILE. Assume FinderInfo to be DirInfo.

       -h, -help, --help
	   Display the help and exit

       -v, -version, --version
	   Show version and exit

NOTE

       There is no way to detect whether FinderInfo is FileInfo or DirInfo. By default, apple_dump examins whether file or directory, a parent
       directory is .AppleDouble, filename is ._*, filename is .Parent, and so on.

       If setting option -f or -d, assume FinderInfo and doesn't look for another file.
