|Operating system||Unix, Unix-like, Plan 9, Inferno|
In computer software, strings is a program in Unix, Plan 9, Inferno, and Unix-like operating systems that finds and prints text strings embedded in binary files such as executables. It can be used on object files and core dumps.
Strings are recognized by looking for sequences of at least 4 (by default) printable characters terminating in a NUL character (that is, null-terminated strings). Some implementations provide options for determining what is recognized as a printable character, which is useful for finding non-ASCII and wide character text.
Using strings to print sequences of characters that are at least 8 characters long (this command prints the system's BIOS information; should be run as root):
dd if=/dev/mem bs=1k skip=768 count=256 2>/dev/null | strings -n 8 | less
