Shell常用命令

 

基本语法

 

while [ 1 ]; do sleep 1; ll; done # 无限循环
while [ $i -lt 10 ]; do echo $i;let "i=$i+1"; done # 有限循环
cat raw.txt | while read line; do echo $line; done # readline
until [ 1 = 0 ]; do sleep 1; ll; done # 无限循环
for i in /media/m* ; do ls -l $i; done # 与目录资源结合
if [ 1 -eq 1 ]; then ll ;fi # test常用判断
if [[ 0 -eq 0 && 1 -eq 0 ]]; then ll ;fi
if [ 0 -eq 0 -a 1 -eq 0 ]; then ll ;fi
if [ ! -e /tmp/111 -a -z "$a" ]; then ll ;fi # 不存在111文件 且a变量长度为0 则执行ll

 

 

 

 

 

常用文本操作命令

 

ps -ef | grep java | grep -v eclipse # 查看进程，筛选出java的，排除eclipse的
echo helloworld | tr -d "o" # 删除字符o，输出 hellwrld
echo 'a:b:c' | tr -s ':' '*' # 替换字符:为*，输出 a*b*c
echo 'a:b:c' | awk -F ':' '{print $1 "+" $3 "+" $2}' # 按:切分后，按下标调整顺序，空格分割输出。a+c+b
awk -F':' '{print $1}' temp2.log | awk '{ arr[$1]++ } END { for( no in arr) { print no , arr[no] } }' | sort -n -t" " -k 2 -r # 一句话实现group by
grep -rn 'ReturnMessageListCount' info.log | awk -F"|" '$3 ==11 {print $0 }'
echo 'a:b:c' | sed -e 's#:#*#g' # 替换字符:为*，输出 a*b*c
zgrep " body size " push-receipt-service-info.1.log.gz | awk '{sum+=$NF}END{print sum}'

 

 

 

 

 

常用命令

 

sudo su admin # 切换为admin身份
sudo -u admin kill -9 xxx # 以admin身份执行kill命令
ps -ef # 查看java进程
zip -9 -p haha -r bak.zip src # 以9级压缩比、haha为密码，压缩src目录，压缩后的文件是bak.zip
gunzip FileName.gz #解压缩

cd /usr/local && jdk-8u144-linux-x64.tar.gz
cd /usr/bin;$pr ln -sf /usr/local/jdk1.8.0_144/bin/java java;

# 开发机有/data目录 不需要创建 
mkdir -p /data/web
ln -s /data/web /web

# 新增用户
groupadd -g 1203 push;
useradd -u 1203 -g 1203 -d /web/push push;
echo 'push123' |passwd --stdin push;
chmod 755 /web/push;
chown -R push.push /data

#添加path

lsof -n|awk '{print $2}'|sort|uniq -c|sort -nr
统计各用户打开句柄数：
lsof -n|awk '{print $3}'|sort|uniq -c|sort -nr
统计各命令打开句柄数：
lsof -n|awk '{print $1}'|sort|uniq -c|sort -nr
统计整个系统打开句柄数：
cat /proc/sys/fs/file-nr
find /proc -print | grep -P '/proc/\d+/fd/'| wc -l
