How about
awk -F, -v"FLDS=5,8" '
BEGIN {FCNT = split(FLDS, FLD)
}

I'll leave it up to you to implement the shell wrapper script, but...
for the 3 fields (5,8 and 12) to be modified, awk should be called as:
awk -v fld='5,8,12' -f hsquared.awk myFile.csv

a bit verbose and can be simplified - just following your description.

awk -v fld='5,8' -f hsquared.awk myFile.csv
where hsquared.awk is:
BEGIN {
FS=OFS=","
fld=(!fld)?"5":fld

Hello H squared,

Please use code tags as per forum rules for commands/Inputs/codes you are using into your posts. If you have an Input_file and you want to print all the lines into reverse order...

Hello H squared,

Following may help you in same.(tested with GNU awk).

awk '($0 ~ /[[:digit:]]/){print;next} ($0 ~ /[[:alpha:]]/){num=split($0, A,"");for(i=1;i<=num;i+=2){Q=Q?Q A[i]:A[i]};Q=Q...

Hi H squared,
That isn't the way arrays work. Reading an array creates elements based on field splitting; not arrays of individual characters. But, both recent versions of bash and 1993 or later...

Hi Haider,
That takes care of the syntax error in your code. But you need to look at post #3 where cero points out the logic error in your code...

Hi,
you see the syntax error because there is a space missing: [$c = $a ] should be [ $c = $a ]. The else branch is never hit because $a either matches $b or it doesn't. Maybe you mixed up the OR...

You need to show us the actual script that you are running; not just something similar to it. The diagnostic you have shown us says there is a problem on line 5 in main.sh, which in the script you...

Hello H squared,

Could you please try following and let me know if this helps you.

awk 'FNR==NR{A[$1]=$1;next} ($1 in A){print $1 >> "similar_ones.txt";delete A[$1];next} !($1 in A){print $1 >>...

Don't pipe through tee but redirect using > .

Unfortunately you don't mention your OS/shell etc. Here's one possible solutionfind . -exec stat -c "%y %F %n" {} + | sort -r | head -1

Hello ,

ls -ltr | grep ^d | head -1 --> Directories
ls -ltr | grep ^-r | head -1 --> Files

Thanks,

Hello Haider,

Not tested though, could you please try following and let us know how it goes. Also make sure while setting this script to crontab you run it to 00:00 AM of your box time.
...

If your script runs every hour, and the serialno resets at 00:00, then you can simply take the current hour as serialno.
The following is suitable for hourly crontab

ext=$(date +"%F").AAAAA$(date...

You ask us to note spaces and tabs, but you didn't use CODE tags (which are required for us to be able to distinguish tabs and multiple spaces from single spaces). You got an email message and an...
