Hi All,

I searched internet for the usage of tr command, honestly it is very powerfull when process flat files,

take text replacement for example

cat file1.txt | tr "abc" "xyz"

the output will be that 'a' change to 'X', 'b' to 'Y', 'c' to 'Z'

but does it support function that can replace "abc" to "xyz", not change them individually?

Please advise which kind of option should I use for tr or any other command in Linux?

thanks

Henry
