Which Way to Recursively Remove Accented Characters from File Names

Question

I tried other scripts I found online (*os I found), but to no avail. So I want to know some of you(s) how to do this automated/recursive task.

Shell Script Taken from: https://tsgii.blogspot.com/

set meta-flag on


set output-meta on


set convert-meta off

#!/bin/bash

NOMBRES_FICHEROS=$(ls)

for i in $NOMBRES_FICHEROS
do
        echo '...TRATANDO EL FICHERO: '$i'...'
        cat $i | tr [:upper:] [:lower:] > def_$i
        cat $i | tr "ÁÉÍÓÚÑ" "AEIOUN" > def_$i
        mv def_$i $i
done

No comments, it didn’t work! Maybe I don’t have Mr. Bash as CLI command interpreter

#!/bin/bash


for file in *;
do
newname=`echo "$file" | iconv -t 'ascii//TRANSLIT'`


mv "$file" "$newname"


done

This other one I found also did not run on my system, I think that could not even the interpreter Bash, only Ash linked to Bash.

#!/bin/sh

for i in *
do
    # ^  Quando esse chapeuzinho aparece no início de uma lista de caracteres significa negação;
    j=`echo "$i" | sed 's/[^A-Za-z0-9_.]//g'`
    # Vai remover todos os acentos das letras indicadas - https://www.vivaolinux.com.br/topico/Shell-Script/Script-para-retirar-acentos
    j=`echo "$j" | sed 'y/áÁàÀãÃâÂéÉêÊíÍóÓõÕôÔúÚçÇ/aAaAaAaAeEeEiIoOoOoOuUcC/'`
    mv "$i" "$j"
    echo "Acento(s) removido de: $i"
done

This has already worked in parts, I say this, because the amendment makes a somewhat strange exchange, even changes characters without accent also [where there is no].

These are the ones I found.

Answer 1

You can use the command iconv. This function will convert characters from one encoding to another. The command is simple.

Contents of a file:

iconv -f UTF8 -t ASCII//TRANSLIT < input.txt > output.txt

Content of a variable:

$psr_new_value = $(echo $psr_variable | iconv -f UTF8 -t ASCII//TRANSLIT)

Explanation of the Command:

 iconv  -f UTF8  -t ASCII//TRANSLIT < input.txt > output.txt

Complete Example:

Below is the structure and code used in the test.

File structure before:

.
├── andré.txt
├── cajá.php
├── joão.txt
├── ñãõ.txt
└── vou_à_praia.txt

0 directories, 5 files

Code:

#/bin/sh

for file in *.txt;
do
    mv $file $(echo $file | iconv -f UTF8 -t ASCII//TRANSLIT)
done

File structure after:

.
├── andre.txt
├── cajá.php
├── joao.txt
├── nao.txt
└── vou_a_praia.txt

0 directories, 5 files
