Disadvantages of Shell Scripting

  1. Inadvertent typing errors such as rm -rf * / (instead of the intended rm -rf */) can cause major disasters by deleting everything on the system.
  2. More errors arise because many UNIX commands differ in name by only one letter: cp, cd, dd, df, etc.
  3. Also, the execution speed of shell scripts is low and so, they are not well suited for large and complex tasks.
