Encontre e substitua uma string se determinado padrão for encontrado em uma linha

Question

Tudo o que preciso fazer é procurar por CCSID nesse arquivo, sempre que encontrar CCSID , o CHAR dessa linha deve ser substituído por NCHAR e VARCHAR nessa linha. com NVARCHAR2 .

Eu tentei usar sed e awk. Mas não consegui encontrar uma maneira perfeita de resolver esse problema.

 CREATE TABLE JCR.ICMSTSYSCONTROL (
            LIBRARYSERVERID  INTEGER NOT NULL ,
            LANGUAGECODE  CHAR(3) CCSID 37 NOT NULL ,

            SYSSEGMENTTHRESHLD  INTEGER NOT NULL ,
            ACLBINDINGLEVEL  SMALLINT NOT NULL ,
            LIBRARYACLCODE  INTEGER NOT NULL ,
            PUBACCESSENABLED  SMALLINT NOT NULL ,

            PATHICMROOT  VARCHAR(128) CCSID 37 NOT NULL ,
            PATHICMDLL VARCHAR(128) CCSID 37 NOT NULL ,
            SUSPENDSERVERTIME  TIMESTAMP DEFAULT NULL ,
            RMSTATUSINTERVAL  SMALLINT NOT NULL ,
            RMSTATUSTIMEOUT  SMALLINT NOT NULL ,
            TIEINTERVAL  SMALLINT NOT NULL ,
            LSCURRENTVERSION  VARCHAR(128) CCSID 37 NOT NULL ,
            TRACEUSER CHAR(175) CCSID 37 DEFAULT NULL ,

            CONSTRAINT JCR.ICMSTSYSCONTROLPK PRIMARY KEY( LIBRARYSERVERID ) )
            ;

A saída deve ser como:

                ;

Como resolver isso?

    

Answer 1

com sed :

sed '/CCSID/ { s/ CHAR(/ NCHAR(/; s/ VARCHAR(/ NVARCHAR2(/ }' file

• O primeiro padrão procura por linhas contendo CCSID . Então a parte dentro de {...} entra em vigor.
  • s/ CHAR(/ NCHAR(/; substitui CHAR( (com espaço na liderança) por NCHAR( .
  • s/ VARCHAR(/ NVARCHAR2(/ e substitua VARCHAR( por NVARCHAR2( .

Answer 2

perl -pe '/CCSID/ and s/\bCHAR\b/N$&/ || s/\bVARCHAR\b/N$&2(/' file
