m Minimum string length. Default is 3
o File to save results to
p Display list of built in regular expressions
q Quiet mode (Do not show header or total number of hits)
s Really Quiet mode (Do not display hits to console. Speeds up processing when using -o)
u If set, look for Unicode strings. Default is true. Use -u false to disable
x Maximum string length. Default is unlimited

bstrings.exe -f "C:\Temp\someFile.txt" --lr guid
bstrings.exe -f "C:\Temp\aBigFile.bin" --fs c:\temp\searchStrings.txt --fr c:\temp\searchRegex.txt -s
bstrings.exe -d "C:\Temp" --mask "*.dll"
bstrings.exe -d "C:\Temp" --ar "[\x20-\x37]"
bstrings.exe -d "C:\Temp" --cp 10007
bstrings.exe -d "C:\Temp" --ls test
bstrings.exe -f "C:\Temp\someOtherFile.txt" --lr cc --sa
bstrings.exe -f "C:\Temp\someOtherFile.txt" --lr cc --sa -m 15 -x 22
bstrings.exe -f "C:\Temp\UsrClass 1.dat" --ls mui --sl
