I have a folder with thousand of images, and I need to cut all the images with a 'F' as a third letter in the filename in another folder. Is there a way to write a bash code to do that? Or how can I do?

Isn't that simply a matter of using globs:

mv source_folder/??F* destination_folder

man bash:

Pattern Matching

Any character that appears in a pattern, other than the special pattern characters described below, matches itself. The NUL character may not occur in a pattern. A backslash escapes the following character; the escaping backslash is discarded when matching. The special pattern characters must be quoted if they are to be matched literally.

The special pattern characters have the following meanings:

*

Matches any string, including the null string. When the globstar shell option is enabled, and * is used in a pathname expansion context, two adjacent *s used as a single pattern will match all files and zero or more directories and subdirectories. If followed by a /, two adjacent *s will match only directories and subdirectories.

?

Matches any single character.

If there are enough of them the command might overwhelm the interpreter, especially on older systems. I've had old ksh shells puke when a command went over 1kb. You might need to use a more complex construction.

find source_folder -name '??F*' -maxdepth 1 | 

   xargs -IF mv F destination_folder

Alternate syntax, probably a lot more efficient -

find source_folder -name '??F*' -maxdepth 1 | 

   xargs mv -t destination_folder

But if possible for you, simple is better. Try Sam's solution first.

Good luck.

Create a .sh file (for example, script.sh) and put the code:

#!/bin/bash

letter_order=3 # Third

search_letter="F" # Find the letter F



for file in *; do

    if [ "${file:$letter_order-1:1}" == "$search_letter" ]; then

        mv ${file} myNewFolderName/

        printf '%sn' "${file}"

    fi

done

So, just run the script '$ ./script.sh'
