i am relatively new to programming. i am trying to use an open source library found by google search. the readme file tells to write make on commandline, as a result i got an exe file sample, but now i am trying to chk the output and the usage is:
USAGE Usage: sample <options> options: -c : Encode input file to output file. -d : Decode input file to output file. -k [1-7] : Length of binary portion. -i <filename> : Name of input file. -o <filename> : Name of output file. -h|? : Print out command line options. -c Compress the specified input file (see -i) using the Lempel-Ziv-Welch encoding algorithm. Results are written to the specified output file (see -o). -d Decompress the specified input file (see -i) using the Lempel-Ziv-Welch decoding algorithm. Results are written to the specified output file (see -o). Only files compressed by this program may be decompressed. -k [1-7] The number of bits in the binary portion of a Rice encoded value. -i <filename> The name of the input file. There is no valid usage of this program without a specified input file. -o <filename> The name of the output file. If no file is specified, stdout will be used. NOTE: Sending compressed output to stdout may produce undesirable results.
i think i sholud give the command ./sample -c -4 -input.txt -output.txt
but i am getting an error. the error gives description of usuage, which means i ma doing something wrong.
any help is appreciated.additionally, if anyone can refer me to some document describing how to give such commands i will be grateful.
