linux查看文件行号
1. cat -n catalina.out
2. less -N catalina.out
3. grep -n "许一借" catalina.out
grep -E "key1|key2|key3"
file.txt 满足任意条件（key1、key2和key3之一）将匹配。
grep key1 file.txt | grep key2 |grep key3
必须同时满足三个条件（key1、key2和key3）才匹配。
4. cat -n catalina.out | grep '员工投资收益积分'
linux 显示一个文件的中间几行
使用cat
1. 从第300行开始，显示100行。即显示300~399行
cat catalina.out | tail -n +300 | head -n 100
2. 显示100行到300行
cat catalina.out| head -n 300 | tail -n +100
注意两种方法的顺序
tail -n 100：显示最后100行
tail -n +100：从100行开始显示，显示100行以后的
head -n 100：显示前面100行
使用sed命令
sed -n '5,10p' catalina.out 这样你就可以只查看文件的第5行到第10行。
