If there was a file like sample_ids.txt with the following text
Sample_Id Alternative_Id
12345 X0987
23456 X9876
34567 X8765
And a bunch of fasta files:
12345.fa
23456.fa
34567.fa
grep -v "Sample_Id" | parallel --colsep "\t" "cp {1}.fa {2}.fa"
Will create the following fasta files:
X0987.fa
X9876.fa
X8765.fa
