Search for a string or an expression in one or several files.
FIND [/c] [/n] [/i] [/v] [/e] string [files ...]
Search for a string or an expression, in one or several files or in the standard input (stdin).
string : The text string or the expression to be searched in files or in the standard input. Unlike Windows native implementation of FIND, Dos9 does not require the use of quotes to delimit string.
files ... : A list of files (that may include regular expression) in which the FIND is to search string. Folders that match regular expressions are ignored. If files is empty, then FIND uses standard input as a file input.
/e : Assume that string is a regular expression. Note that FIND searched lines that match the full regular expression.
/c : Count the number of line matching string and only print this number.
/n : Print line numbers of matching lines.
/i : Use case insensitive search.
/v : Reversed search; search lines that does not contain string or does not match the regular expression.
Obviously, the /c and /n switches can not be mixed. If FIND encounters /c and /n switches together, does will take account of the last specified switches.
The FIND command has no line length limit, unlike Windows implementation which supports a maximum length of about 1024 characters.
The FIND command is not designed to handle binary files. However FIND is perfectly able to search in a binary file as long as it does not contain any NULL character.
In order to specify a string to search that contain quotes, use the escape character ^ before the quotes to escape.
Although Windows' FIND is an external command, Dos9's FIND is an internal command. Under WINDOWS you can use the native command from Windows using the ALIAS command.
Compatible with cmd.exe.
