wc -c

Count the number of bytes in a file

wc -c counts bytes. Used to verify file sizes: confirm a backup file is non-zero, check a config file wasn't truncated. A 0-byte file means the write failed.

Example

$ wc -c /etc/nginx/nginx.conf
2789 /etc/nginx/nginx.conf

Tip: Type it yourself in the terminal below - reading is not the same as doing.
