How can you find and replace text in a file using the Windows command- line environment? Note- Be sure to see the update at the end of this answer for a link to the superior JREPL. BAT that supersedes REPL. BATJREPL. BAT 7. 0 and above natively supports unicode (UTF- 1. LE) via the /UTF option, as well as any other character set, including UTF- 8, via ADO!!!! I have written a small hybrid JScript/batch utility called REPL. BAT that is very convenient for modifying ASCII (or extended ASCII) files via the command line or a batch file. Command Line. Feature. Version 5.0. Version 6.0 /ACCTXREF. Cross reference a code for the Chart of Accounts Description field in QuickBooks /ADDR_LINE5. I am writing one script. it will run one linux machine. its targets includes linux, solaris and windows. I know that i can use scp to copy files between *nix. but how. This hands-on guide demonstrates how the flexibility of the command line can help you become a more efficient and productive data scientist. You'll learn how to. Using the command line, I'd like to copy one directory to another. For example there is directory C:/test and C:/test2. I'd like to copy C:/test into C:/test2 so that.The purely native script does not require installation of any 3rd party executeable, and it works on any modern Windows version from XP onward. It is also very fast, especially when compared to pure batch solutions. REPL. BAT simply reads stdin, performs a JScript regex search and replace, and writes the result to stdout. Here is a trivial example of how to replace foo with bar in test. REPL. BAT is in your current folder, or better yet, somewhere within your PATH: type test. The JScript regex capabilities make it very powerful, especially the ability of the replacement text to reference captured substrings from the search text. I've included a number of options in the utility that make it quite powerful. For example, combining the M and X options enable modification of binary files! The M Multi- line option allows searches across multiple lines. The X e. Xtended substitution pattern option provides escape sequences that enable inclusion of any binary value in the replacement text. The entire utility could have been written as pure JScript, but the hybrid batch file eliminates the need to explicitly specify CSCRIPT every time you want to use the utility. Here is the REPL. BAT script. Full documentation is embedded within the script.@if (@X)==(@Y) @end /* Harmless hybrid line that begins a JScript comment. Documentation ***********. REPL. BAT version 6. REPL Search Replace [Options [Source. Var]]. : :: REPL /?[REGEX|REPLACE]. Performs a global regular expression search and replace operation on. Each parameter may be optionally enclosed by double quotes. The double. : :: quotes are not considered part of the argument. The quotes are required. The quotes should also be used if the argument contains a. If called with a single argument of /?, then prints help documentation. If a single argument of /? REGEX, then opens up Microsoft's. JScript regular expression documentation within your browser. If a single. : :: argument of /? REPLACE, then opens up Microsoft's JScript REPLACE. If called with a single argument of /V, case insensitive, then prints. REPL. BAT. : :: Search - By default, this is a case sensitive JScript (ECMA) regular. JScript regex syntax documentation is available at. Replace - By default, this is the string to be used as a replacement for. Full support is provided for. JScript replace method. For example, $& represents the portion of the source that matched. A $ literal. : :: can be escaped as $$. An empty replacement string must be represented as "". Replace substitution pattern syntax is fully documented at. US/library/efy. 6s. Options - An optional string of characters used to alter the behavior. REPL. The option characters are case insensitive, and may. A - Only print altered lines. Unaltered lines are discarded. If the S options is present, then prints the result only if. The A option is. : :: incompatible with the M option unless the S option is present. B - The Search must match the beginning of a line. Mostly used with literal searches. E - The Search must match the end of a line. Mostly used with literal searches. I - Makes the search case- insensitive. J - The Replace argument represents a JScript expression. The expression may access an array like arguments object. However, $ is not a true array object. The $. length property contains the total number of arguments. The $. length value is equal to n+3, where n is the. Search string. : :: $[0] is the substring that matched the Search. Arguments $[0] through $[1. Argument $[1. 1] and above must use the square. L - The Search is treated as a string literal instead of a. Also, all $ found in the Replace string. M - Multi- line mode. The entire contents of stdin is read and. This also enables preservation of the original. If the M option is not present, then every. The M option is incompatible with the A option unless the S. Note: If working with binary data containing NULL bytes. M option must be used. S - The source is read from an environment variable instead of. The name of the source environment variable is. Without. : :: the M option, ^ anchors the beginning of the string, and $ the. With the M option, ^ anchors the beginning. V - Search and Replace represent the name of environment. An undefined. : :: variable is treated as an empty string. X - Enables extended substitution pattern syntax with support. Replace string. : :: \\ - Backslash. Backspace. : :: \f - Formfeed. Newline. : :: \q - Quote. Carriage Return. : :: \t - Horizontal Tab. Vertical Tab. : :: \xnn - Extended ASCII byte code expressed as 2 hex digits. Unicode character expressed as 4 hex digits. Also enables the \q escape sequence for the Search string. The other escape sequences are already standard for a regular. Search string. : :: Also modifies the behavior of \xnn in the Search string to work. ASCII byte codes. Extended escape sequences are supported even when the L option. Both Search and Replace support all of the extended. X and L opions are combined. Return Codes: 0 = At least one change was made. V option was used. No change was made.

IMPORTANT UPDATEI have ceased development of REPL. BAT, and replaced it with JREPL. Useful Command- line Commands on Windows(Not really a command per- se, but a way to get there.)For those of you that find yourself going to Start > Run > "cmd" a lot, you can cut down some steps. Say you want to get your IP address. You would normally go Start > Run > "cmd" [enter]. Now instead, go.. Start > Run > "cmd /k ipconfig"This will run cmd and the command 'ipconfig', and it will keep the window open. So if I want to quickly get my MAC address (physical address), I'd do: cmd /k ipconfig /all. All courtesy of Boston.
