linux 之 xargs 使用技巧

# grep命令接受管道传参> cat /etc/passwd | grep root
# echo命令不接受管道传参> echo "hello rumenz" | echo
# 将标准输入转为命令行参数> echo "hello rumenz" | xargs echohello rumenz

# 空格作为分隔符$ echo "one two three" | xargs mkdir
# 指定制表符\t作为分隔符$ echo -e "a\tb\tc" | xargs -d "\t" echoa b c

> echo 'one two three' | xargs -p touchtouch one tow three ?...y

> find /path -type f -print0 | xargs -0 rm

> xargs -L 1 find -name"*.txt"./1.txt./rumenz.txt./2.txt./3.txt

> echo {0..9} | xargs -n 2  echo 

# 将命令行参数传给多个命令> cat foo.txtonetwothree
> cat foo.txt | xargs -I {} sh -c 'echo {}; mkdir {}'onetwothree
> lsone two three

> cat rumenz.txt1 2 3 45 67 8 9> cat rumenz.txt | xargs1 2 3 4 5 6 7 8 9

> cat rumenz.txt1 2 3 4 5 6 7 8 9> cat rumenz.txt | xargs -n 31 2 34 5 67 8 9

> echo "rumenz:123:rumenz:456:rumenz:789" | xargs -d : -n 2rumenz 123rumenz 456rumenz 789

> find . -type f -name "*.txt" -print | xargs rm -f

> cat rumenz.txt | xargs wget -c
