anthager / transfer.sh

Last active April 14, 2020 10:40

Script for transferring files over ssh when scp is not available. Right now it only works with single files and single level directories and file permissions are ignored. You could prob do some fancy recursive shit for nested directories

	#!/usr/bin/env bash
	# $1 (first argument) should be the directory you want to transfer
	set -e
	tmp_file="tmp-file"
	folder=""
	path=""

	[[ -e $tmp_file ]] && rm $tmp_file
	[[ -d $1 ]] && path=$1 && folder=$(echo $path \| rev \| cut -d '/' -f 2 \| rev) && echo "mkdir $folder" >>$tmp_file
