Question

How can I eliminate syntax error in command line? I created a bash script like this:

#!/bin/bash

USER="$@"

sed  s/[!@#$%^&*()]//g > $@
done

if ! [ -f $@ -a -r $@ ] ; then
 echo "Wrong Option : "${USER}" is not readable or not exist" >&2
 exit -1
fi

cat "${@}"|while read -r line
do
IFS=, read -r f1 f2 f3 f4 f5 <<< "$line"
mysql --user=user --password=password --database=database <<EOF
INSERT INTO table_name VALUES($f1, $f2 , $f3 , $f4 ,$f5);
EOF
done

并且我对其他终点站执行这一规定:

$ ./script.sh test!rr.txt
-bash: !rr.txt: event not found

Actually, this is a script which insert data from text files to database table. and as you can see, I want to check file existence before insert text files.

我试图利用tr——指挥和指挥,以消除指挥线上的yn误,但我认为这行不通。

我期望:

$ ./script.sh test!rr.txt
Wrong Option : test!rr.txt is not readable or not exist

Do you have any idea? Thanks.

在试图评价这一路线之前,她将<代码>!解释为历史指挥。提审:

$ ./script.sh test!rr.txt

Answer 2

如果你想在档案中包含血清特征,请在上面引述:

$ ./script.sh  test!rr.txt

Answer 3

你需要调整你们的期望。 Bash只是做你告诉它的事情:在把论点传给你的文字之前,进行历史扩张。关于援引“......”论点或其他理由的其他答案是正确的,但是它们认为,在把论点传给你的文字之前,历史扩张正在发生(在你可以核实档案存在的地方)。

Answer 4

2. 引言中的参数是为了防止空壳解释特殊标志:

$ ./script.sh "test!rr.txt"
