Replace characters in string with awk gsub

Hi I have a source file that looks like

a,b,c,d,e,f,g,h,t,DISTI(USD),MSRP(USD),DIST(EUR),MSRP(EUR),EMEA-DISTI(USD),EMEA-MSRP(USD),GLOBAl-DISTI(USD),GLOBAL-MSRP(USD),DISTI(GBP), MSRP(GBP) 

I want to basically change MSRP(USD) to MSRP,USD and DIST(EUR) to DIST,EUR and likewise for all i'm using the following command and able to replace "(" with , but not sure if i can use multiple replace inside gsub.

awk 'NR==1{for(i=10;i<=NF;i++){gsub(/\(/,OFS,$i);A=$i}; print $A}' OFS=',' FS=',' sample.txt

Thanks

What output are you getting? gsub should replace every match it finds.

EDIT: Although since you're passing in one field at a time it will only ever find 1 match in this case anyway...

Whether like this ?

$ cat file
a,b,c,d,e,f,g,h,t,DISTI(USD),MSRP(USD),DIST(EUR),MSRP(EUR),EMEA-DISTI(USD),EMEA-MSRP(USD),GLOBAl-DISTI(USD),GLOBAL-MSRP(USD),DISTI(GBP), MSRP(GBP)

$ awk 'NR==1{gsub(/\(/,",");gsub(/\)/,x)}1' file

Resulting

a,b,c,d,e,f,g,h,t,DISTI,USD,MSRP,USD,DIST,EUR,MSRP,EUR,EMEA-DISTI,USD,EMEA-MSRP,USD,GLOBAl-DISTI,USD,GLOBAL-MSRP,USD,DISTI,GBP, MSRP,GBP

Need / insist on awk? If not, try

tr -s '()' ',' <file
