The strings command returns each string of printable characters (ASCII)
|
|
in files. Its main uses are to determine the contents of and to extract text
|
|
from binary files (i.e., non-text files). From the Shell manual: "find the
|
|
printable strings in a object, or other binary, file".<br>
|
|
|
|
Strings can be used to extract character information and string of a given lenght
|
|
from text file(s). When used without any options, strings displays all strings
|
|
that are at least four characters in length in the files whose names are
|
|
supplied as arguments (i.e., input data). Strings that are on separate lines
|
|
in the input files are shown on separate lines on the screen, and an attempt
|
|
is made to display all strings found on a single line in a file on a single
|
|
line on the screen (although there may be a carryover to subsequent lines in
|
|
the event that numerous strings are found on a single line). strings looks in
|
|
all sections of the object files except the (__TEXT,__text) section.<br>
