大家下午好，我有两个这样的文件：
文件 1
45.999 60.9999
70.000 23.0090
文件 2
DATAFILE
pheno.txt
TRAITS
FIELDS_PASSED TO OUTPUT
WEIGHT(S)
RESIDUAL_VARIANCE
EFFECT
2 cross alpha
EFFECT
1 cross alpha
RANDOM
animal
FILE
pedigree.txt
SNP_FILE
snp_.txt
(CO)VARIANCES
并且需要像这样为文件 2 的特定位置传递文件 1 的值：
文件 2
DATAFILE
pheno.txt
TRAITS
FIELDS_PASSED TO OUTPUT
WEIGHT(S)
RESIDUAL_VARIANCE
45.999
EFFECT
2 cross alpha
EFFECT
1 cross alpha
RANDOM
animal
FILE
pedigree.txt
SNP_FILE
snp_.txt
(CO)VARIANCES
23.0090
记住，我想保留文件 2，只需添加文件 1 的值
set -- $(<file1)
sed -i "/RESIDUAL_VARIANCE/{n;c
};${s/[0-9].*//;t;a
}" file2
另见 man sed:
-i edit files in place
