[英]Use Bash to Read File Then Do “grep” with The Line Against The File Itself
I am trying to read a file using Linux Bash and then use "grep" to run that line against the file itself. 我正在尝试使用Linux Bash读取文件,然后使用“grep”对文件本身运行该行。 It seems not working to me...
这似乎对我不起作用......
#!/bin/bash
path=$1
while read line
do
var1=$(grep $line $path)
echo $?
exit
done < $path
The $? $? returns 1. What's going on here?
返回1.这里发生了什么?
使用grep -F
(固定字符串)代替:
var1=$(grep -F "$line" "$path")
