linux:如何在每行的开头添加一个前缀字符串
# If you want to edit the file in-place sed -i -e 's/^/prefix/' file # If you
want to create a new file sed -e 's/^/prefix/' file > file.new
基本的替换
:s/vivian/sky/ #替换当前行第一个 vivian 为 sky :s/vivian/sky/g #替换当前行所有 vivian 为 sky
:n,$s/vivian/sky/ #替换第 n 行开始到最后一行中每一行的第一个 vivian 为 sky :n,$s/vivian/sky/g #替换第
n 行开始到最后一行中每一行所有 vivian 为 sky # (n 为数字,若 n 为 .,表示从当前行开始到最后一行) :%s/vivian/sky/
#(等同于 :g/vivian/s//sky/) 替换每一行的第一个 vivian 为 sky :%s/vivian/sky/g #(等同于
:g/vivian/s//sky/g) 替换每一行中所有 vivian 为 sky # 过滤输出 cat 20200927-9-10_1983712 |
