lhunath 1205238450 learn $var; rm $file -- If you do not quote $var bash will split its content up into words, *removing* ALL whitespace (newlines, spaces, tabs) from it. Each word is fed as a separate argument to echo or rm. Echo prints all its arguments separating them by a SINGLE space while rm will remove the files denoted by every WORD.

kojiro 1296058112 learn echo outputs a string, but if that string starts with a - it could break. printf '%s\n' is a little safer. Also consider using a herestring: see !<<<

ormaaj 1348597119 learn echo outputs a string. It is very non-portable except in simple cases, and should never be used with option flags. In POSIX shells, use: `printf '%b\n' "args"' or `printf %s "args"' for echo -e and -n respectively. For ksh-like shells other than Bash, use `print', `print -r', and `print -n'. http://wiki.bash-hackers.org/commands/builtin/echo | http://cfajohnson.com/shell/cus-faq.html#Q0b |
