If your AWK command has an error, then this clobbers the file, a better |
| 11 |
variant, with die, would be: |
| 12 |
awk "$@" "$f" >"${tmpf}" || die "awk failed..." |
| 13 |
cp -f "${tmpf}" "$f" || die "copy back failed" |
| 14 |

This calling format is also a problem if they intended to pass multiple |
| 17 |
files to the command, or if they do so accidentally. |

Eg, an unprotected glob in the first argument, eg: |
| 20 |
eawk foo* '/foobar/{$1="x"; print $0}' |
| 21 |
|
| 22 |
If foo1 and foo2 existed, this would be considered as: |
| 23 |
awk foo2 /foobar/{$1="x"; print $0}' foo1 |
| 24 |
|
| 25 |
which really will NOT have the desired effect. |
