can I pass awk variable to system command?
I wanna use a system function to deal with several data. So I use awk variable FILENAME to transfer the file directory to system command, but it does not work.
I use a shell function "out_function" to deal with data and save the result in another directory with the same file name.
How can I do it?
My code is as follows:
#try.awk
{system("./out_function FILENAME > ./dst/FILENAME")
print FILENAME
nextfile
}
I use command ---awk -f try.awk ./src/* --- to open data files. I found that system("
command") could not recongnize FILENAME, so it could not run correctly. How
ever, my test command--print FILENAME-- runs correctly.
How should I do to solve this problem? Thanks a lot.
