sed pattern range
Hi guys, trying to replace a '#' with a ' ' (space) but only between the brackets '(' and ')'

Code:
N="text1#text2#text3(var1#var2#var3)"

N=`echo $N |sed '/(/,/) s/#. //'`

echo $N

Looking for an output of "text1#text2#text3(var1 var2 var3)"

Any ideas?

Code:
awk 'BEGIN{
 string = "text1#text2#text3(var1#var2#var3)"
 start = index(string,"(")
 end = index(string,")")
 tochange=substr(string,start,end-start+1)
 gsub("#","",tochange)
 print substr(string,1,start-1) tochange

}
'

Hi guys, had a few days off Smilie

Code:
awk 'BEGIN{
 string = "text1#text2#text3(var1#var2#var3)"
 start = index(string,"(")
 end = index(string,")")
 tochange=substr(string,start,end-start+1)
 gsub("#"," ",tochange)
 print substr(string,1,start-1) tochange

}
'

works fine if the string is text i.e:

string = "text1#text2#text3(var1#var2#var3)"

but not so happy if I want to swap the text to the variable i.e:

Code:

N="text1#text2#text3(var1#var2#var3)"
awk 'BEGIN{
 string = "$N"
 start = index(string,"(")
 end = index(string,")")
 tochange=substr(string,start,end-start+1)
 gsub("#"," ",tochange)
 print substr(string,1,start-1) tochange

}
'

Ideas?

if you study and know awk inside out, you don't need to do it in bash.
anyway, to pass shell variable to awk, use the -v option....

Thanks for that ghostdog74, all working now.

Code:
N="text1#text2#text3(var1#var2#var3)"

awk -v stringvar=$N 'BEGIN{
 string = stringvar
 start = index(string,"(")
 end = index(string,")")
 tochange=substr(string,start,end-start+1)
 gsub("#"," ",tochange)
 print substr(string,1,start-1) tochange

}
'

output: text1#text2#text3(var1 var2 var3)

sorry to bump but looking for help with a slightly different input.

Tried changing parts around but a bit stumped.

N="text1#text2#text3(var1#var2#var3)" has changed to
N="text1#text2#text3(var1#var2#var3)#text4(var4#var5#var6)"

at the moment with the current script to output (with either input) is:

output: text1#text2#text3(var1 var2 var3)

and I need:

output: text1#text2#text3(var1 var2 var3)#text4(var4#var5#var6)

any ideas guys?
