Hi there
I'm new to this forum:
I was wondering if someone could help me figure out a task

In the second field, change 'f' to female and 'm' to male globally. Display the first 9 lines.

Use 2 sed statements one piped to another.
Note use of single quotes in examples.

This was my output

[sjim7@hills ~]$ grep -k2 |sed 's/m/male/g' famous.data | sed 's/f/female/g' | head -n 9
grep: invalid option -- 'k'
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
01 male maleotzart amaleadeous 25 2nd 94233
02 male guthrie woody 23 2nd 94223
03 female simaleone nina 27 2nd 94112
04 male lennon john 29 2nd 94221
05 female harris emalemaleylou 20 2nd 94222
06 male malearley bob 22 2nd 94112
07 female malearley rita 26 2nd 94212
08 female warwick dione 26 2nd 94222
09 male prine john 35 3rd 94321

How would i type it to focus on the second column to change the m to males, and f to females , instead of changing every letter in each column that has a m to male , thanks
