This is not such a context. echo "$INPUT" > The ISSUE is when the string Contain "*" the results are very estrange. or > "*[space]" This is PRECISELY why you must quote your variable expansions. If you fail to quote them, the results undergo word splitting and pathname expansion. This is what you are seeing. Always quote your variable expansions. echo "$INPUT"
