Count number of instances of a character and use it in a condition
I have a csv file (t.txt) in which some lines have 7 commas and some have 8
If the line has 8 commas, I want to remove the 2nd comma in that line.
Any suggestions? I have been trying
if [[awk -F "," '{print NF-1}' == 8]]; then sed 's/,//2'; t.txt
awk replace condition

Welcome to SO, it is always recommended to add sample of Input and expected output along with your efforts in your post in CODE TAGS{}button, you could do so now.

Since you haven't provided samples of Input_file or expected output so couldn't test, could you please try following.
echo "a,a,a,d,f,g,h,h,f" |
awk '
match($0,/,[^,]*/){
print substr($0,1,RSTART-1) substr($0,RSTART,RLENGTH) substr($0,RSTART+RLENGTH+1)
next
}
1'
a,aa,d,f,g,h,h,f
In case you want to check 8 commas condition too then replace match with match($0,/,[^,]*/) && NF==9 to above code too.
