Please upload the patch into your Magento root directory and run the appropriate SSH command:
For patch files with the file extension .sh:
sh patch_file_name.sh
Example: sh PATCH_SUPEE-1868_CE_1.7.0.2_v1.sh

Eu fiz o upload do arquivo de correção PATCH_SUPEE-2518_CE_1.5.1.0-1.7.0.2_v1.sh

Para o diretório raiz do magento (public_html /) e receba este erro na execução.

root@atlas [/home/public_html/]# sh PATCH_SUPEE-2518_CE_1.5.1.0-1.7.0.2_v1.sh
: command not found_1.5.1.0-1.7.0.2_v1.sh: line 7:
'ATCH_SUPEE-2518_CE_1.5.1.0-1.7.0.2_v1.sh: line 9: syntax error near unexpected token `{
'ATCH_SUPEE-2518_CE_1.5.1.0-1.7.0.2_v1.sh: line 9: `_check_installed_tools() {

A linha 9 no arquivo de patch .sh é

_check_installed_tools() {
local missed=""

until [ -z "$1" ]; do
    type -t $1 >/dev/null 2>/dev/null
    if (( $? != 0 )); then
        missed="$missed $1"
    fi
    shift
done

echo $missed

Não consigo ver um erro nesse arquivo ou entender o que está causando isso. Alguém mais tem esse problema ou sabe alguma coisa sobre isso?
