How do I run a gawk file with spaces in the path name?

I think it will be a case of providing quotes in the command string: command = "gawk" command = command " -v version=\"" dataArray[1] "\"" command = command " -v date=\"" dataArray[2] "\"" command = command " -v platform=\"" dataArray[3] "\"" command = command " -f \"" INSTALLATION_LOCATION_GAWK "generateSanity_Scripts/removeData.awk\"" command...
AWK - Search for a pattern-add it as a variable-search for next line that isn't a variable & print it + variable
I'd say awk '/\.pp/ { if(NR != 1) print line; line = $0; next } NF != 0 && substr($1, 1, 1) != "#" { line = line $0 } END { print line }' filename This works as follows: /\.pp/ { # if a line contains ".pp" if(NR !=...
Using awk on multiple input files
I wouldn't use Awk for this. while IFS=, read -u 3 filename lines; do head -n "$lines" >"$filename" done 3<other.csv <main.csv The read -u to read from a particular file descriptor is not completely portable, I believe, but your question is tagged bash so I am assuming that is not...
Design the output with awk or gawk script
Instead of print you can use printf. Change the END{} part of your awk script as follows: END {for (i in a) {printf "%d\t%d\n", i, a[i]};} Between the two values (%d) it prints a tab (\t) and at the end a newline (\n). Or your complete command: for file in...

Using Gawk and Printf in a Bash script
bash,scripting,printf,file-handling,gawk
Ignoring the issue of the outer loop and focusing on the awk part of the question, you can use sprintf to produce your filename: gawk -v RS="START_of_LINE_to_SEPARATE" 'NF{ file = sprintf("new_file_%04d.txt", ++n) print RS$0 > file }' "$i" The format specifier %04d means that the number is a digit, padded...

normalize column data with maximum value of that column
Let's take this as the sample input file: $ cat >file 1 5 2 2 3 7 4 6 This awk script will normalize the second column: $ awk 'FNR==NR{max=($2+0>max)?$2:max;next} {print $1,$2/max}' file file 1 0.714286 2 0.285714 3 1 4 0.857143 This script reads through the input file twice....
Printing the compared result under last column header
To avoid having header updated, change awk's expression to the following: 'FNR==NR{a[$1]=$7;next} FNR==1{print $0; next} {print (($1 in a) ? $0","a[$1] : $0",NA");}' In this case 1st line of the file1.txt will be printed as is, without any changes.

$ awk 'FNR==NR{a[$1]=1;next} a[$3]==0' file1 FS='["|]+' file2 "b"|"124"|"ind" "d"|"122"|"aus" How it works: file1 FS='["|]+' file2 This list of files tells awk to read file1 first, then change the field separator to any combination of double-quotes and vertical bars and then read file2.

Confusing backslash before awk, what does it mean?
Either the book contains a typo, or the script was incompletely transcribed. A backslash may optionally be used for line wrapping: echo "moo" | \ wc -l which is equivalent to echo "moo" | wc -l but in this particular case, the backslash is completely optional after a pipe, so...

How to select range for two operations?
