DOS Equivalent of GREP

September 22nd, 2008

In Unix you can pipe the output of a command into the GREP command in order to only display the lines that contain a required string.  This is means you don’t have to scroll through pages of output to find the bit you’re interested in.  The DOS equivalent of GREP is FIND:

Searches for a text string in a file or files.

FIND [/V] [/C] [/N] [/I] [/OFF[LINE]] "string" [[drive:][path]filename[ ...]]

/V         Displays all lines NOT containing the specified string.
/C         Displays only the count of lines containing the string.
/N         Displays line numbers with the displayed lines.
/I         Ignores the case of characters when searching for the string.
/OFF[LINE] Do not skip files with offline attribute set.
"string"   Specifies the text string to find.
[drive:][path]filename
Specifies a file or files to search.

If a path is not specified, FIND searches the text typed at the prompt
or piped from another command.

this can be useful with the netstat command:

netstat -ano | find /i ":80"

or when viewing the DNS cache:

ipconfig /displaydns | find /i "google"

Although that isn’t ideal since the output of ipconfig isn’t really formatted to play nicely with the find command.
