文件

MO_CIF_INP TRO_MO_CIF_INP

BP_LINKED_TETES TRO_BP_LINKED_TETES

MO_BPID TRO_MO_BPID

MO_INP_BPRESP TRO_MO_INP_BPRESP

上述脚本的输出是

ioiufeioru

dehdueuh TRO_MO_INP_BPRESP

我的目的是只替换匹配的单词，而不是 MO_CIF_INP438替换上述情况下的所有单词。我们如何使用单词搜索？我尝试了以下情况，但没有成功

1.

nawk 'NR==FNR { a[$1]=$2 ; next} {for ( i in a) gsub(/i/,a[i])}1' file.dat 1.txt


TRO_BP_LINKED_TETESoTRO_BP_LINKED_TETESufeTRO_BP_LINKED_TETESoru

2.

nawk 'NR==FNR { a[$1]=$2 ; next} {for ( i in a) gsub(\<i\>,a[i])}1' file.dat 1.txt
nawk: syntax error at source line 1
 context is
        NR==FNR { a[$1]=$2 ; next} {for ( i in a) >>>  gsub(\ <<< <i\>,a[i])}1
nawk: illegal statement at source line 1

您可以尝试以下方法：

awk '

# Read entire file.dat in an array indexed at column1 having value of column2

NR==FNR { 
    a[$1]=$2; 

# Skip the next action statements until file.dat is completely stored

    next 
}

# For each index element of array

{
    for(i in a) { 

# Iterate over each values of line from 1.txt file

        for(x=1;x<=NF;x++) {

# If an exact match is found replace it with array element else leave it as is. 

            $x=(i==$x)?a[i]:$x
            }
        }
}1' file.dat 1.txt


$ head file.dat 1.txt 
==> file.dat <==
MO_CIF_INP TRO_MO_CIF_INP

BP_LINKED_TETES TRO_BP_LINKED_TETES

MO_BPID TRO_MO_BPID

MO_INP_BPRESP TRO_MO_INP_BPRESP
