count files

files

For each file, count determines the number of lines, words, and characters in the file. A word is defined as a sequence of characters delimited by one or more blanks or tabs, or by the end of a line. If count is run on more than one file, each output line is identified by the file name, and a final output line gives the total number of lines, words, and characters in all files.

1. Count the number of lines, words and characters in all files in the current directory with the extensions ".x" and ".h".

cl> count *.[xh]

2. Count the number of .x files in the current directory.

cl> dir *.x op=1 | count

3. Count the number of set environment definitions.

cl> set | count

4. Count the number of references to the READ function in all .x files in the current directory.

cl> match "read#(" *.x | count
