If they didn't work with $ the first time, they won't work with $ the second, third, or fourth time. $ has a different meaning in awk anyway, it means column. Smilie

awk doesn't substitute variables inside strings, they have to be outside. You can concatenate strings and variables just by listing them in order though, so almost as easy.

Try this, with the variables outside double quotes:

Code:
"/dummy/history/history." PMONTH "." PFYEAR;

Libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness. Qrencode is a utility software using libqrencode to encode string data in a QR Code and save as a PNG or EPS image. OPTIONS
-h, --help display help message. -o FILENAME, --output=FILENAME write image to FILENAME. If '-' is specified, the result will be output to standard output. If -S is given, structured symbols are written to FILENAME-01.png, FILENAME-02.png, ... (suffix is removed from FILENAME, if specified) -s NUMBER, --size=NUMBER specify the size of dot (pixel). (default=3) -l {LMQH}, --level={LMQH} specify error collectin level from L (lowest) to H (highest). (default=L) -v NUMBER, --symversion=NUMBER specify the version of the symbol. (default=auto) -m NUMBER, --margin=NUMBER specify the width of margin. (default=4) -d NUMBER, --dpi=NUMBER specify the DPI of the generated PNG. (default=72) -t {PNG,EPS,ANSI,ANSI256}, --type={PNG,EPS,ANSI,ANSI256} specify the type of the generated image. (default=PNG) -S, --structured make structured symbols. Version must be specified. -k, --kanji assume that the input text contains kanji (shift-jis). -c, --casesensitive encode lower-case alphabet characters in 8-bit mode. (default) -i, --ignorecase ignore case distinctions and use only upper-case characters. -8, --8bit encode entire data in 8-bit mode. -k, -c and -i will be ignored. -M, --micro encode in a Micro QR Code. (experimental) -V, --version display the version number and copyrights of the qrencode. [STRING] input data. If it is not specified, data will be taken from standard input. EXAMPLES
qrencode -l L -v 1 -o output.png 'Hello, world!' encode into a symbol version 1, level L. qrencode -iSv 1 --output=output.png read standard input and encode it into a structured-appended symbols in case-insensitive mode. AUTHOR
