问题描述
我收到一个错误 ./test.sh: line 13: [: missing `]' in the file test.sh我尝试使用括号和其他选项,例如 -a 或通过检查文件 p1 的大小,但错误始终存在并且始终执行 else 语句,而不管给定的输入如何.我什至尝试通过删除 ;在第 13 行,但没有帮助.
I am getting an error ./test.sh: line 13: [: missing `]' in the file test.sh I tried using brackets and other options such as -a or by checking the size of the file p1 but the error is always there and the else statement is always executed irrespective of the input given.I even tried by removing the ; in line 13 but it didn't help.
test.sh
#!/bin/bash
echo "Enter app name"
read y
$y &
top -b -n 1 > topLog.log
#-w checks for the whole word not and sub string from that word
grep -w "$y" topLog.log > p1
#-s option checks if the file p1 is present or not
if [ -s "p1"]; #line 13
then
echo "Successful "
else
echo "Unsuccessful"
fi
rm p1
我是 bash 脚本的新手.所以如果有任何愚蠢的错误,请原谅.
I am new to bash scripting.So if there is any silly mistake please excuse me.

if [ -s "p1"]; #line 13
