it this possible in bash script

[packets]

I'm a doing a script. There are some part of the script that I need to do but don't know how to do it.

If I have a text which contains:

foo,fee,fii,fuu

Could I rearrange it to:

foo
fee
fii
fuu

I don't know if sed can do this. There are some function of sed that I just recently discovered but I don't know if it can do the scenario above.

I'm currently checking a tool/command that could help me do this thing just wandering if there's anyone out there that could suggest on how I could accomplish this.

sed can do this, right.

But you can also use tr in order to replace ',' by newline ('\n').

sed -i 's/,/\n/g' YOUR-FILE.txt

This one do the trick

If string is in a variable try this.

foo=foo,fee,fii,fuu 

echo $foo | sed 's/,/\n/g'

if you are using some kind of modern shell, eg bash, ksh etc, they already have internal capabilities to string manipulation

$  text="foo,fee,fii,fuu"
$ IFS=","
$ set -- $text
$ echo $1
foo
$ echo $2
fee
$ for((i=1;i<=${#};i++))
> do
>  eval echo \$${i}
> done
foo
fee
fii
fuu
