-l
The number of lines in each input file is written to the standard output.
To get the number of lines from a single file as a number:
cat file.txt | wc -l | awk '{print $1}'
-c
The number of bytes in each input file is written to the standard output. This will cancel out any prior usage of the -m option.
wc -c somefile.txt | awk '{print $1}'
To test non-zero length file, use bash test -s.
-m
The number of characters in each input file is written to the standard output. If the current locale does not support multibyte characters, this is equivalent to the -c option. This will cancel out any prior usage of the -c option.
-w
The number of words in each input file is written to the standard output.
