Searching within Text

• findstr: Search for strings in files.

  • /I: Ignore case.
  • /S: Searches for matching files in the current directory and all subdirectories.
  • /V: Print only lines that do not contain a match.

  C:\> findstr "search_term" file.txt
  This line contains the search_term.
  

```bash
C:\> findstr /I "Search_Term" file.txt
This line contains the search_term.
```

Filtering and Transforming Text

• There's no direct equivalent to awk in Windows, but you can use PowerShell or other scripting languages for similar tasks.

• powershell -Command "(Get-Content file.txt) -replace 'World', 'Universe'": Use PowerShell to replace text.
  

  C:\> echo Hello World | powershell -Command "$input -replace 'World', 'Universe'"
  Hello Universe

Sorting and Counting

• sort: Sort input.

  C:\> echo banana & echo apple & echo cherry | sort
  apple
  banana
  cherry

• There's no direct uniq equivalent in Windows, but you can use PowerShell for similar tasks.
• find /c /v "": Count lines in a file.

  C:\> echo Hello World | find /c /v ""

Text Display

  C:\> type file.txt
  This is the content of file.txt.
