Without this option if the search string contains multiple words, separated with spaces, then findstr will return lines that contain either word (OR). Options used by the findstr command in the example above: Option While the former may give you: filename1:7:line with regex in 10-line file filename2:2:another regex line. Use this command to quickly locate patterns without any wildcard characters, useful when searching for.

PS C:\> Get-Alias | Out-String -Stream | Select-String "curl" 4.The egrep command allows the use of extended regular expressions while grep only searches for the matching word or term that the user specified in the command. If a command in PowerShell returns some objects, before parsing, they should be converted to strings using the Out-String -Stream command: # Windows CMD PS C:\> netstat -na | Select-String " PORT" My instance of man (1) parallel actually says this. The egrep command in Unix shell scripting is owned by the family of the grep command that is used for searching and matching a specific pattern in Unix. ![]() If find has the -print0 predicate (most do) it would be preferable to use find. Grep the output of a netstat command for a specific port: # Windows CMD use -coloralways to preserve the grep color (this is true whenever you are using grep in a pipe as well) Jim. The egrep command is just like grep, but uses a different (extended) language for regular expressions. In a Windows PowerShell the alternative for grep is the Select-String command.īelow you will find some examples of how to “grep” in Windows using these alternatives.Ĭool Tip: Windows touch command equivalent in CMD and PowerShell!
