Re: Una de shell scripting

[Pere Nubiola Radigales <pere@nubiola.cat>]

Jo personalment prefereixo fer servir
M=$(echo|sed s/món/gent/)
Els accents oberts es veuen poc

Ara bash permet simplificar lo anterior
proba M=${M/món/gent}

 ${parameter/pattern/string}
              The  pattern is expanded to produce a pattern just as in pathname expan‐
              sion.  Parameter is expanded and the longest match  of  pattern  against
              its  value  is  replaced  with  string.   If Ipattern begins with /, all
              matches of pattern are replaced with string.  Normally  only  the  first
              match  is  replaced.   If  pattern  begins  with #, it must match at the
              beginning of the expanded value of parameter.  If pattern begins with %,
              it  must match at the end of the expanded value of parameter.  If string
              is null, matches of pattern are deleted and the / following pattern  may
              be  omitted.   If  parameter  is  @  or *, the substitution operation is
              applied to each positional parameter in turn, and the expansion  is  the
              resultant list.  If parameter is an array variable subscripted with @ or
              *, the substitution operation is applied to each member of the array  in
              turn, and the expansion is the resultant list.

Hola Pau,

No si vols dir això:

export M=`echo $M | sed s/món/gent/`

Salut

Vado
