yes of course.
Er..

I have a text file named "test.txt"
which store a text file as follow

1|2|3|4|
2|3|4|5|
3|4|5|6|

and i need to replace those text file into these:
1|2|3|4|;2|3|4|5|;3|4|5|6|;

can I still use awk?

But what have you tried ?

this replaces the last "|" in the input
Code:
awk '{ sub(/\|$/, ";"); print }END{ printf "\n" }' ORS="" filename


try this for the required output
Code:
awk '{ print }END{ printf "\n" }' ORS=";" a2

Code:
# tr "\n" ";" < file
1|2|3|4|;2|3|4|5|;3|4|5|6|;4|5|6|7|

if leave to you to put in the last ";" . i suggest you also read up more on shell scripting.

Code:
$ cat test.txt 
1|2|3|4|
2|3|4|5|
3|4|5|6|
4|5|6|7|
$ nawk 'sub(/\|$/,";")' ORS= test.txt 
1|2|3|4;2|3|4|5;3|4|5|6;4|5|6|7;$

If you want the last newline:

Code:
$ nawk 'sub(/\|$/,";");END{printf "\n"}' ORS= test.txt 
1|2|3|4;2|3|4|5;3|4|5|6;4|5|6|7;
