我想要创建一个shell脚本，它将以读取第一个文件的方式读取这些文件，并在severe1中提取严重的行，然后提取warning1中的警告行。然后传递第二个文件，以便severe2中的严重行，然后warning2中的警告行与最后一个文件(10个文件)相同。做这件事最简单的方法是什么？

我检查的方式如下：**

for i in (ls *.log); do
cat *.log|grep "SEVERE" > severe$i.txt
cat *.log|grep "WARNING" > warning$i.txt
done;

**

Answer 1

您的代码有几个问题：

for i in (ls *.log); do

• 而不是(...)，它应该是$(...)，但是根本不需要它，因为.
• 的输出不应该解析ls，而不是使用for f in *.log; do
• 您的$i不是计数器，而是文件名，您必须手动添加计数器。循环和增量之前的i=0，例如循环中的i=$((i+1))。(然后使用for f in *.log)。

cat *.log|grep "SEVERE" > severe$i.txt

虽然这本身并不是“错误”的，但在这种情况下仍然存在问题。

• grep从文件中读取，不需要cat：grep -h“严厉”*.log > severe$i.txt
• 当您希望每个文件中的消息分开时，为什么要阅读*.log？
• 要提高性能，请将-F选项添加到grep中。
• 若要不匹配错误的模式，而只匹配整个单词，请添加-w。
• 好习惯是将变量文件名双引号-> ... > "severe$i.txt"。

所以，总的来说，我会：

i=0
for f in *.log; do
    i=$((i+1))
    grep -Fw "SEVERE" "$f" > "severe$i.txt"
    grep -Fw "WARNING" "$f" > "warning$i.txt"
done

或者全部放在一个awk中：

awk '
    FNR==1{FILENUM+=1}
    /^SEVERE/{print > "severe"FILENUM".txt"}
    /^WARNING/{print > "warning"FILENUM".txt"}
' *.log
