Full Discussion: Replacing first field of file2 with the second filed of file1 for matching cases

Don't use double quotes around the filenames (i.e. file[12]) as they need to be expanded by the shell. Assuming a typo in your samples' first lines, I'd suggest "replacing field 1 in file 2 with field 2 in file 1 if both files' field 1 match":
Code:
awk -F";" 'FNR==NR{T[$1]=$2; next} $1 in T {$1=T[$1]} 1' OFS=";" file[12]
