Help: removing a variable substring from a string variable in sh script
I'm a programmer, but a *nix noobie. Im writing a script that needs to do the following:
Magic Happens Here
#note: Item_to_be_removed may be item 1 ... itemN, which should be removed the same as this example's item2.
#note2: Item_to_be_removed may be something not even in the list_string, in which case it should fail silently (because that is actually the case we are hoping for)
I'm just not sure what the Magic function is/how to format it
List_String=`echo List_String | sed 's/$Item_to_be_removed//g'` ?
I could just write a compiled program that would do this one function, but I'm certain that there is a better/more elagent way already built in that I can call from the shell script.
Currently looking into awk script.
Thanks in advance,
