- Write a Go program that takes three arguments: the name of a text file, and two strings. This utility should then replace every occurrence of the first string in the file with the second string. For reasons of security, the final output will be printed on the screen, which means that the original text file will remain intact.
- Use the encoding/gob package to serialize and deserialize a Go map, as well as a slice of structures.
- Create a Go program that handles any three signals you choose.
- Create a utility in Go that replaces all tab characters found in a text file with a given number of spaces, specified as a command-line parameter to the program. Once again, the output will be printed on the screen.
- Develop a utility that reads a text file line by line and removes the space characters from each line using the strings.TrimSpace() function.
- Modify kvSaveLoad.go in order...
