Linux下Shell脚本替换换行符(转)

说明:过滤换行符确实有点吭,不是那么好弄。处理文本时需要将换行符替换为空格,若使用sed命令会比较麻烦,而使用tr命令非常方便。 

输入文本(country.txt)

China
America
France
German

sed命令

cat country.txt | sed ':label;N;s/\n/ /;b label'

tr命令

cat country.txt | tr "\n" " "

两个命令输出一致,但是sed命令的输出结尾有换行符,而tr命令的输出结尾没有换行符

China America France German
