script to replace a character with '(Apostrophe)

Hi Friends,

I need a sed or awk based script to replace a character(alphabet) with ' (Apostrophe). I tried to use the following two commands

1) sed -e 's/a/'/' filename
2) awk '{sub("a","'",$1);print}' filename

but both got failed.
Any help on this.

Thanks in advance..

You're close, you can do it with:

sed -e "s/a/'/" filename (note the quote types.)

Another way with tr :
Code:
tr a "'" <infile
