Remove only specific char on every line when exists

Hi
I need to remove "|" char when it's the last char of the line.

Input file:

generoso|desprendido|altruista|
abnegar|ceder|sacrificar|
abocetado-da|esbozado|
apuntado|insinuado|incompleto
abocetar|esbozar|bosquejar|
dise�ar|delinear

------------------------ output need ---

generoso|desprendido|altruista
abnegar|ceder|sacrificar
abocetado-da|esbozado
apuntado|insinuado|incompleto
abocetar|esbozar|bosquejar
dise�ar|delinear

I have searched in the forum but only find solutions that delete last char of all lines,

Thanks

Try:

sed 's/|$//' file

try also:

awk 1 RS="[|]*\n" infile

Hi,

Not working with large file about 50.000 lines, it's that possible?

Thx

What is not working?

Nothing change in my output file.

getting out original content of test11, it's my large file, in the same format. Maybe it's malformed, how can i fix that file?

Thx

How about

sed 's/@$//' file

then?

--
The awk statement will only work with gawk or mawk, but not with regular awk, because regular awk can only use a single character in RS.

Not working it's very strange I think my file it's malformated

Do you have windows control chars in that file, like <CR> at the end of line? Post a few lines of cat -et file output...

Infile

Ok, fixed, I made a little script that read line by line (bad file) and insert on a new file. Then was able to remove last char when exists.

#!/bin/bash

count=1




while read -r line ; do 

    
 echo $(echo $line) >> clean.txt
       
                 
done < test10

sed 's/@$//' clean.txt >> clean2.txt

Thx

THERE you are! Use Scrutinizer's proposal, slightly extended:

sed 's/@\r$//' file

Not sure if your sed accepts that \r notation; in bash, try <ctrl>V<ctrl>M, then...

\r would work in GNU sed, but not in regular sed.

With regular sed you could

sed "s/@$(printf "\r")\$//"

or, knowing that every line ends in \r\n just:

sed 's/@.$//'
