How To Batch Change File Names

This was my first workable attempt at doing batch renaming:

Use this simple PowerShell script to change hundreds or thousands of file names automatically, based on a CSV. As part of a scientific experiment, I had a large number of.JPG images files that I needed to match up to individual plants. Rename Files Ever since the earliest DOS versions the RENAME and its 'twin' (or alias?) REN have been around to allow us to change file names: REN or RENAME Renames a file or files. Batch rename files by finding and replacing terms in the filename I had a set of files that have a common naming scheme and I wantd to replace a word common to all the filenames with another word. Unix-style shell utilities make it easy to do this sort of batch rename operation by finding and replacing patterns in filenames. To batch rename files, just select all the files you want to rename, press the F2 button (alternatively, right-click and select rename) and then enter the name you want and press the enter button. What the above action does is take the file name you specified and adds a number to each file name. Fire your copy of Microsoft Excel or Google Docs Spreadsheets and paste those file names into the first spreadsheet column. Step 4: In the blank adjacent column, add a corresponding Excel function - for instance, use SUBSTITUTE to change specific text in the filenames, use CONCATENATE with DATE if you want to add date to the filename, etc.

The command works as follows:

Batch Rename File

ls -1 *foo* lists all the files in the current directory with foo in the file name. It lists one filename per line.
The ouptut is piped to awk '{print('mv '$1 ' ' $1)}' command. This produces new output where each line is mv FILENAME FILENAME, with FILENAME being the corresponding filename.
The output from the awk command is piped to sed 's/foo/bar/2', which replaces the second instance of foo in a line with bar. The second instance of foo corresponds to the second FILENAME in the mv FILENAME FILENAME lines generated by the awk command. This creates output of the form mv FILENAME NEWFILENAME, where the new filename is desired filename with foo replaced with bar.
Finally, the entire output is saved to rename.txt for user review to ensure that the rename commands are being generated correctly. As with the main batch rename technique, you could pipe the output to /bin/bash but this is not recommended.

This technique has some caveats. The first is that since it does not work with file names with spaces. The awk command prints the first field $1 in each line of input, and the spaces in the file name causes the first word of the filename to be treated as the entire first field.

The second is that since sed replaces the second instance of foo in a line, it does not handle the case where the file name had multiple instances of foo Globalprotect app download. in the first place. For example, if you had a file named “foofoo.jpg”, then the corresponding command generated by the above code would be:

6x48 herringbone hatch pattern. The second foo is replaced with bar, which is not what you want. Thus, this technique does not work when there is more than one instance of the word you want to replace in the filename.
