using AWK printf with userdefine variables

seems simple but i've not been successfull in adding the value of a Variable to a every line of a file using AWK & printf
i've come up with the following, but it's not working.:mad:

--- mydatafile.dat

e.g. of data in file:

cau_actvty_fa_lrf.ksh
fan_soco_fa.ksh
ny_sum_lst.ksh
etc....

myvar_path=$PWD

awk -v PATH=$myvar_path '{printf("%s\nPATH",$0)}' mydatafile.dat

output is to be: value of $PWD before each file name

awk -v PATH="$myvar_path"  '{printf( PATH "%s\n",$0)}' mydatafile.dat

thanks...

but how would i then put a / after the value of PATH which will be between the filename and it's path :confused: it doesn't seem that PATH gets a formating expression since it's comming before the formatting expressions.... bear with me as i'm still learning the nuances of awk...:slight_smile:

awk -v PATH="$myvar_path" '{printf( PATH "%s\n",$0)}' mydatafile.dat

i figured out another way too, but a bit more involved

awk '{printf("%s/%s\n","'"${myvar_path}"'",$1)}' mydatafile.dat

this way i was able to insert a / after the value of ${myvar_path}

Thanks again for your time.

Just put one there:

awk -v PATH="$myvar_path"  '{printf( PATH "/%s\n",$0)}' mydatafile.dat

PATH is part of the format string.

Awesome.... i didn't realize you could put something before the %s

Thanks again, little by little , my little understanding is getting bigger.

thanks.
