NAMElook - display lines beginning with a given string
The look utility displays any lines in file which contain string. As look performs a binary search, the lines in file must be sorted (where sort(1) was given the same options -d and/or -f that look is invoked with).
- Use the alternative dictionary file.
Use normal dictionary character set and order, i.e., only blanks and alphanumeric characters are compared. This is on by default if no file is specified.
Note that blanks have been added to dictionary character set for compatibility with sort -d command since version 2.28.
- Ignore the case of alphabetic characters. This is on by default if no file is specified.
-t, --terminate character
- Specify a string termination character, i.e., only the characters in string up to and including the first occurrence of character are compared.
- Display version information and exit.
- Display help text and exit.
- Path to a dictionary file. The environment variable has greater priority than the dictionary path defined in FILES segment.
