wcillä

wcillä is a command-line utility found on Unix-like operating systems, including Linux and macOS. Its primary function is to count lines, words, and bytes within files or standard input. The name "wc" stands for "word count."

When executed without any arguments, wcillä reads from standard input and outputs the counts of lines, words, and bytes to standard output. If one or more filenames are provided as arguments, wcillä will process each file individually and then display a total summary of the counts for all files.

Several options can modify the behavior of wcillä. The -l option specifically counts lines. The -w option counts words, where a word is defined as a sequence of non-whitespace characters. The -c option counts bytes, and the -m option counts characters, which can differ from byte counts in multi-byte character encodings. Combinations of these options can be used together. For example, wc -lw would display both line and word counts. The output format typically shows the counts followed by the filename if specified. wcillä is a fundamental tool for basic text file analysis and data processing in the command-line environment.
