I have a loop that processes a bunch of files within a dir. I would like to input the filename into the file it processes, but I'm getting an error. It works perfectly with the myvar syntax but I need that for obvious reasons.
awk: cmd. line:1: RS= awk: cmd. line:1: ^ unexpected newline or end of string for filename in $files do awk -v "myvar=${filename}" RS= '/-- Ticket/{++i; print "PROMPT myvar Line ", i ORS $0 ORS; i+=split($0, a, /\n/)+1}' ${filename}.txt done Couple of issues here, use the -v syntax for each of the variables that you are trying to pass to awk,
awk -v myvar="${filename}" -v RS= '/-- Ticket/{++i; print "PROMPT " myvar " Line ", i ORS $0 ORS; i+=split($0, a, /\n/)+1}' ${filename}.txt # ^^^ variable1 ^^^^^ variable2 --> using separate -v for each should be right approach.
For a shell variable import to awk do it as in my example above, not as "myvar=${filename}" but just myvar="${filename}"
awk: cmd. line:1: RS= awk: cmd. line:1: ^ unexpected newline or end of string
PROMPT myvar Line but it's not printing myvarawk -v myvar="${filename}" -v RS= '/-- Ticket/{++i; print "PROMPT "myvar" Line ", i ORS $0 ORS; i+=split($0, a, /\n/)+1}' ${filename}.txtIf you could avoid a batch loop, it's better (performance mainly for subshell fork, ...)
# assume TXT_files is the list of $files with .txt extension (not purpose of this OP) awk RS='' ' /-- Ticket/{ # get the file name without extension myvar = FILENAME;sub( /\.txt$/,"",myvar) print "PROMPT " myvar " Line " ++i ORS $0 ORS i += split( $0, a, /\n/) + 1 } ' ${TXT_files} 
awk -v myvar="$filename" -v RS= '/-- Ticket/{++i; print "PROMPT", myvar, "Line ", i ORS $0 ORS; i+=split($0, a, /\n/)+1}' "$filename.txt"
