AECI,919998546783,A2,B4,的 NOMATCH ,, WSF
备注
答案 0 :(得分:1)
尝试类似:
awk '
NR==FNR{
for(i=2; i<=NF; i++) A[$i]=$1
next
}
{
$5="NOMATCH"
for(i in A) if ($2~"^" i) $5=A[i]
}
1
' FS='[=,]' file1 FS=, OFS=, file2

如果您有GNU awk
,请尝试以下操作。像:
awk -f script.awk file1.txt file2.txt
script.awk
的内容:
BEGIN {
FS="[=,]"
OFS=","
}
FNR==NR {
for(i=2;i<=NF;i++) {
a[$1][$i]
}
next
}
{
$5 = "NOMATCH"
for(j in a) {
for (k in a[j]) {
if (substr($2,0,6) == k) {
$5 = j
}
}
}
}1
或者,这是单行:
awk -F "[=,]" 'FNR==NR { for(i=2;i<=NF;i++) a[$1][$i]; next } { $5 = "NOMATCH"; for(j in a) for (k in a[j]) if (substr($2,0,6) == k) $5 = j }1' OFS=, file1.txt file2.txt
结果:
aec,919922783456,a5,b3,DL,,asf
abc,918975583456,a1,b1,MH,,abf
aeci,919998546783,a2,b4,NOMATCH,,wsf
如果您有“旧”awk
,请尝试以下操作。像:
awk -f script.awk file1.txt file2.txt
script.awk的内容:
BEGIN {
# set the field separator to either an equals sign or a comma
FS="[=,]"
# set the output field separator to a comma
OFS=","
}
# for the first file in the arguments list
FNR==NR {
# loop through all the fields, starting at field two
for(i=2;i<=NF;i++) {
# add field one and each field to a pseudo-multidimensional array
a[$1,$i]
}
# skip processing the rest of the code
next
}
# for the second file in the arguments list
{
# set the default value for field 5
$5 = "NOMATCH"
# loop though the array
for(j in a) {
# split the array keys into another array
split(j,b,SUBSEP)
# if the first six digits of field two equal the value stored in this array
if (substr($2,0,6) == b[2]) {
# assign field five
$5 = b[1]
}
}
# return true, therefore print by default
}1
或者,这是单行:
awk -F "[=,]" 'FNR==NR { for(i=2;i<=NF;i++) a[$1,$i]; next } { $5 = "NOMATCH"; for(j in a) { split(j,b,SUBSEP); if (substr($2,0,6) == b[2]) $5 = b[1] } }1' OFS=, file1.txt file2.txt
结果:
aec,919922783456,a5,b3,DL,,asf
abc,918975583456,a1,b1,MH,,abf
aeci,919998546783,a2,b4,NOMATCH,,wsf
