Find and replace a particular term in multiple files

sed -i.bak 's/searchword/replaceword/g' file*.txt
# Or sed -i.bak '/searchword/s/searchword/replaceword/g' file*.txt

With bash 4.0, you can do recursive search for files

#!/bin/bash
shopt -s globstar
for file in **/file*.txt
do 
  sed -i.bak 's/searchword/replaceword/g' $file
  # or sed -i.bak '/searchword/s/searchword/replaceword/g' $file
done

Or with GNU find

find /path -type f -iname "file*.txt" -exec sed -i.bak 's/searchword/replace/g' "{}" +;

How to replace a string in multiple files in linux command line

cd /path/to/your/folder
sed -i 's/foo/bar/g' *

Occurrences of "foo" will be replaced with "bar".

On BSD systems like macOS, you need to provide a backup extension like -i '.bak' or else "risk corruption or partial content" per the manpage.

cd /path/to/your/folder
sed -i '.bak' 's/foo/bar/g' *

Finding and replacing text in multiple files within a folder

Cleaned up:

Sub ProcessFiles()
    
    Dim wordApp As Word.Application
    Dim wdDoc As Word.document
    Dim strPath As String, allfiles As Collection, fPath

    strPath = GetFolderPath()
    If Len(strPath) = 0 Then Exit Sub
    
    Set allfiles = GetAllFiles(strPath, "*.doc*")
    If allfiles.Count = 0 Then
        MsgBox "No Word files found"
        Exit Sub
    End If
    
    Set wordApp = New Word.Application
    wordApp.Visible = True
    
    'loop over found files
    For Each fPath In allfiles
        Debug.Print "Processing " & fPath
        Set wdDoc = wordApp.documents.Open(fPath)
        
        ReplaceDocContent wdDoc, ".", " "
        ReplaceDocContent wdDoc, ",", " "
        ReplaceDocContent wdDoc, "~", " "
        'etc.....
        
        wdDoc.Close True 'close and save changes
    Next fPath
    
    MsgBox "done"
End Sub

'replace text in a Word document with some other text
Private Sub ReplaceDocContent(doc As Word.document, findWhat, replaceWith)
    With doc.Range.Find
        .Text = findWhat
        .Replacement.Text = replaceWith
        .Execute Replace:=wdReplaceAll
    End With
End Sub

'collect all files under folder `strPath` which match `pattern`
Private Function GetAllFiles(ByVal strPath As String, pattern As String) As Collection
    Dim objFile As Object, col As New Collection
    'Create an instance of the FileSystemObject and list all files
    For Each objFile In CreateObject("Scripting.FileSystemObject").GetFolder(strPath).Files
        If objFile.Path Like pattern Then col.Add objFile.Path
    Next objFile
    Set GetAllFiles = col
End Function

'return selected folder path or empty string
Function GetFolderPath() As String
    With Application.FileDialog(msoFileDialogFolderPicker)
        If .Show <> 0 Then GetFolderPath = .SelectedItems(1)
    End With
End Function

find and replace strings in files in a particular directory

You can use the sed expression:

sed 's/throw some::lengthy::exception();/throw CreateException(some::lengthy::exception());/g'

And add it into a find command to check .h, .cpp and .hpp files (idea coming from List files with certain extensions with ls and grep):

find . -iregex '.*\.\(h\|cpp\|hpp\)'

All together:

find . -iregex '.*\.\(h\|cpp\|hpp\)' -exec sed -i.bak 's/throw some::lengthy::exception();/throw CreateException(some::lengthy::exception());/g' {} \;

Note the usage of sed -i.bak in order to to edits in place but create a file.bak backup file.

Variable pattern

If your pattern varies, you can use:

sed -r '/^throw/s/throw (.*);$/throw CreateException(\1);/' file

This does the replacement in the lines starting with throw. It catches everything after throw up to ; and prints it back surrounded by CreateException();`.

Test

$ cat a.hpp 
throw some::lengthy::exception();
throw you();
asdfasdf throw you();
$ sed -r '/^throw/s/throw (.*);$/throw CreateException(\1);/' a.hpp 
throw CreateException(some::lengthy::exception());
throw CreateException(you());
asdfasdf throw you();

Find and replace a string within multiple files contained within a directory using a .bat file

You probably want [SS64]: FOR /R.

Small example:

script00.bat:

@echo off

setlocal enableextensions disabledelayedexpansion

set _ROOT_DIR=".\dir0"

for /R %_ROOT_DIR% %%f in (*.config) do (
    echo file: %%f
    rem Do the rest
)

Output:

[cfati@CFATI-5510-0:e:\Work\Dev\StackOverflow\q068684288]> tree /f /a
Folder PATH listing for volume SSD0-WORK
Volume serial number is AE9E-72AC
E:.
|   script00.bat
|
\---dir0
    +---dir0
    |       file.config
    |
    +---dir1
    |       file.config
    |
    \---dir2
            file.config

[cfati@CFATI-5510-0:e:\Work\Dev\StackOverflow\q068684288]> script00.bat
file: e:\Work\Dev\StackOverflow\q068684288\dir0\dir0\file.config
file: e:\Work\Dev\StackOverflow\q068684288\dir0\dir1\file.config
file: e:\Work\Dev\StackOverflow\q068684288\dir0\dir2\file.config

find and replace string from multiple files in a folder using python

Here's a solution using os, glob and ntpath. The results are saved in a directory called "output". You need to put this in the directory where you have the .c and .h files and run it.

Create a separate directory called output and put the edited files there:

import glob
import ntpath
import os

output_dir = "output"

if not os.path.exists(output_dir):
    os.makedirs(output_dir)

for f in glob.glob("*.[ch]"):
    with open(f, 'r') as inputfile:
        with open('%s/%s' % (output_dir, ntpath.basename(f)), 'w') as outputfile:
            for line in inputfile:
                outputfile.write(line.replace('Version1', 'Version2.2.1'))

Replace strings in place:

IMPORTANT! Please make sure to back up your files before running this:

import glob

for f in glob.glob("*.[ch]"):
    with open(f, "r") as inputfile:
        newText = inputfile.read().replace('Version1', 'Version2.2.1')

    with open(f, "w") as outputfile:
        outputfile.write(newText)

Replacing a String In Multiple Files With Their Filename

Something like this?

Get-ChildItem -Filter "*.txt" | ForEach-Object {
  $Path=$_.FullName; (Get-Content $Path) -replace 'unamed', $_.BaseName | Set-Content $Path 
}
