是否将java版本结果追加到上面的行？
是否将java版本结果追加到上面的行？
提问于 2018-08-28 01:25:10
有没有一种方法可以在上面的行后面加上"java版本或许可被拒绝“这一行，在它们之间加一个？我希望在用于red hat 6的bash上实现数据操作目的。
谢谢

使用bash
while true; do
IFS= read -r line1
IFS= read -r line2
IFS= read -r line3
status=$?
printf "%s, %s\n%s\n" "$line1" "$line2" "$line3"
(( status != 0 )) && break
done < file和awk
awk '
/java version/ || /Permission denied/ {printf ", %s\n\n", $0; next}
{printf "%s", $0}
' file
# which can also be written as
awk '{
format = (/java version/ || /Permission denied/) ? ", %s\n\n" : "%s"
printf format, $0
}' file或者，通过操作输入/输出字段和记录分隔符
awk '
BEGIN {FS="\n"; RS=""; OFS=", "; ORS="\n\n"}
{$1 = $1; print}
' file
# or, more tersely
awk '{$1=$1}1' FS='\n' RS='' OFS=', ' ORS='\n\n' file页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
