Question

有没有一种方法可以将“ java版本或权限被拒绝”行添加到上面的行中，并在它们之间添加？？我正在为Red Hat 6的bash上的数据处理目的执行此操作。

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

或者通过操纵输入/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

将Java版本结果附加到上面的行吗？
