The command tells only what the file looks like, not what it is (in the case where file looks at the content). It is easy to fool the program by putting a magic number into a file the content of which does not match it. Thus the command is not usable as a security tool other than in specific situations.
The main Go distribution includes tools for building, testing, and analyzing code: go build, which builds Go binaries using only information in the source files themselves, no separate makefiles; go test, for unit testing and microbenchmarks as well as fuzzing; go fmt, for formatting code; go install, for retrieving and installing remote packages
The length of a string is found by searching for the (first) NUL. This can be slow as it takes O( n ) ( linear time ) with respect to the string length. It also means that a string cannot contain a NUL (there is a NUL in memory, but it is after the last character, not in the string).
Prints a command to the terminal as Bash reads it. Bash reads constructs all at once, such as compound commands which include if-fi and case-esac blocks. If a set -v is included within a compound command, then "verbose" will be enabled the next time Bash reads code as input, ie, after the end of the currently executing construct. [108]

A control block is a data area with a predefined structure, very similar to a C struct, but typically only related to system's functions. A DCB may be compared to a FILE structure in C, but it is much more complex, offering many more options for various access methods .
Ctrl+l : Clears the screen content (equivalent to the command clear). Ctrl+n : recalls the next command (equivalent to the key ↓). Ctrl+o : Executes the found command from history, and fetch the next line relative to the current line from the history for editing. Ctrl+p : recalls the prior command (equivalent to the key ↑).
File descriptors for a single process, file table and inode table. Note that multiple file descriptors can refer to the same file table entry (e.g., as a result of the dup system call [3]: 104 ) and that multiple file table entries can in turn refer to the same inode (if it has been opened multiple times; the table is still simplified because it represents inodes by file names, even though an ...
