Your organization's Linux support team uses Bash scripts for routine automation. You are documenting a new script that backs up user home directories each night. To help other technicians quickly recognize the file as a shell script, which filename extension should you assign to the script?
.vbs
.ps1
.bat
.sh
On Unix and Linux systems, files containing shell (Bourne-compatible) commands are typically saved with the .sh extension so that their purpose is immediately clear. While a shebang (#!) line actually determines the interpreter, the .sh suffix is a familiar visual cue. The other extensions identify scripting languages native to Windows: .ps1 is for PowerShell, .bat for traditional batch files, and .vbs for VBScript-none of which are normally used for Linux shell scripts.
