我有以下 bash 脚本，它提供了一个 Zentiy TUI 来将数据插入数据库。
#!/bin/bash
tip_run1="$(zenity --entry --text "ENTER number of tip runs:" --entry-text "1")"
a=1
until
[[ $tip_run1 -lt $a ]]
do
input="$(zenity --forms --title="table tip_run" --text="Add a new tip run" --separator="," \
--add-entry="ENTER start_time, e.g. 8:20: " \
--add-entry="ENTER finish_time, e.g. 12:30: " \
--add-entry="ENTER weight in kg, -t numeric: "\
--add-entry="ENTER a note, -t text: ")"
psql -tA -U chh1 -d crewdb -c "SELECT SETVAL('tip_run_tip_runid_seq', (SELECT MAX(tip_runid) FROM tip_run), true);" >/dev/null 2>&1
startt="$(echo "$input" | awk -F, -v OFS=, '{print $1}')"
finisht="$(echo "$input" | awk -F, -v OFS=, '{print $2}')"
st="$( date --date="$startt" +%s 2>/dev/null )"
ft="$( date --date="$finisht" +%s 2>/dev/null )"
if [ -n "$st" -a "$ft" ] ; then
startt="$(date +%H:%M -d "$startt" )"
finisht="$(date +%H:%M -d "$finisht" )"
tzdiff="$(( ft - st ))"
else
tzdiff=0
fi

do
var2="$(zenity --forms --title="start_time and/or finish_time are incorrect" --text "Add a start_time and a finish_time" --separator="," \

echo "INSERT INTO tip_run (date_linkid, start_time, finish_time, weight, note) VALUES (${out:1});" >> /tmp/crew.txt
let a++
done
我知道脚本的各个组件都可以工作，但是当我运行它时，我收到以下错误消息：
./tip_run.txt: line 64: set: --: invalid option
set: usage: set [-abefhkmnptuvxBCHP] [-o option-name] [--] [arg ...]
第 64 行位于以下位置：
62 input="$((IFS=, read -r b c d e ; echo "${b}ttt,${c}ttt,${d}xxx,${e}www" )< <<"$input")"
63
64 IFS=,; set -f; set --$input; out=
65 for i in "$@"; do
66
67 case "$i" in
我尝试了 set 的不同选项，但似乎都没有。任何人都可以让我走上正确的轨道吗？
