I want to extract 27092011084688 (value from 4th line, 3rd column).

I used awk 'NR==4' but it gave me whole 4th line.

Answer 1

One way using awk:

awk -F, 'NR==4 { print $3 }' file.txt

Answer 2

$ sed -n "4p" somefile.csv | cut -d, -f3

Edit

What's this?

• -n turns of normal output
• 4p prints the 4th row
• -d, makes cut use , as delimiter
• -f3 makes cut print the 3rd field

Answer 3

Fairly straightforward:

awk -F',' 'NR == 4 { print $3 }' somefile.csv

Using , as a field separator, take record number 4 and print field 3 in somefile.csv.

Answer 4

Use the following:

awk -F ',' 'NR==4 {print $3}'

Answer 5

perl alternative to print element 3 on line 4 in a csv file:

perl -F, -lane 'print $F[2] if $. == 4' somefile.csv
