Unix 基于星号字符（*）连接行
我有一个文本文件，其中有几行以“I”开头，一些以“u>I”开头，另一些为“？”，并且在这些行下面总是有两行，我想将这两行（附加）与具有“anywhere”的行连接起来 尝试了awk、sed，但没有得到可以解决此问题的确切字符串 文件数据：-Unix 基于星号字符（*）连接行,unix,awk,sed,gawk,Unix,Awk,Sed,Gawk,我有一个文本文件，其中有几行以“I”开头，一些以“u>I”开头，另一些为“？”，并且在这些行下面总是有两行，我想将这两行（附加）与具有“anywhere”的行连接起来 尝试了awk、sed，但没有得到可以解决此问题的确切字符串 文件数据：- *i 80.95.226.72/29 n/a None 193.105.101.26

awk无论任何行中的字段数是多少，解决方案都是：

/\*/{ if (p) print p; p=coalesce()}0
function coalesce(){

NF && p && !/\*/ { # if nr of fields > 0, not containing
# '*' and p is set
p = p OFS coalesce(); next # add formatted $0 to p
}
/\*/{ # if $0 contains '*'
if (p) print p; # if p then print it
p=coalesce() # initialize p

如果行/记录/行至少有一个字段（NF
中没有字段
记录），然后重新编译记录，因为当您执行$1=$1
（或任何
对字段的其他赋值）它会导致记录重新编译，其中$0
重建时，将每个FS
替换为OFS
/\*/{s=$0；next}
如果行包含*
，则将变量s
分配为当前值
记录/行/行，然后转到下一行

如果设置了变量s
，并且记录至少有1个字段和变量
n
大于或等于变量c++
（++
增量
运算符），然后连接变量s

等于变量n
，则打印变量s
