want to replace \ in pig latin using replace command

Question

I have a file having data like below in pig

<"{\"action\": \"ac_data\",\"data\":{\"nn1\":\"0000000\",\"zerosquare\":\"newuser\",\"nacde\":\"catlogue\",\"user123\":\"99000200340904\",\"lcadq\":\"89148000001972298094\",\"reserve\":\

And I want to remove \ and the output should be as below

<"{"action": "ac_data","data":{"nn1":"0000000","zerosquare":"newuser","nacde":"catlogue","user123":"99000200340904","lcadq":"89148000001972298094","reserve":

Answer 1

Input :

<"{\"action\": \"ac_data\",\"data\":{\"nn1\":\"0000000\",\"zerosquare\":\"newuser\",\"nacde\":\"catlogue\",\"user123\":\"99000200340904\",\"lcadq\":\"89148000001972298094\",\"reserve\":\

Pig Script :

A = LOAD 'input.csv' as line;  
B = FOREACH A GENERATE REPLACE(line,'([\\\\]+)','');  
dump B;  

Output :

(<"{"action": "ac_data","data":{"nn1":"0000000","zerosquare":"newuser","nacde":"catlogue","user123":"99000200340904","lcadq":"89148000001972298094","reserve":)
