如何使用Bash脚本遍历两个文件 [英] How to use Bash script to loop through two files
本文介绍了如何使用Bash脚本遍历两个文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个包含以下名称的文件(file_in.txt
):
I have a file (file_in.txt
) containing these names:
aphid_splitseq.1.fasta.annot.xml
aphid_splitseq.2.fasta.annot.xml
aphid_splitseq.3.fasta.annot.xml
aphid_splitseq.4.fasta.annot.xml
aphid_splitseq.5.fasta.annot.xml
,我还有另一个文件(file_out.txt
),其名称为:
and I have another file (file_out.txt
) with these names:
aphid_splitseq_1
aphid_splitseq_2
aphid_splitseq_3
aphid_splitseq_4
aphid_splitseq_5
现在我想要这样的语句
java -cp *:ext/*: es.blast2go.prog.B2GAnnotPipe -in aphid_splitseq.1.fasta.annot.xml -out results/aphid_splitseq_1 -prop b2gPipe.properties -v -annot -dat
基本上,我想遍历每个file_in.txt
和file_out.txt
并将-in
和-out
的值分别替换为i
和j
.
Basically, I want to loop through each of file_in.txt
and file_out.txt
and replace the values of -in
and -out
with i
and j
respectively.
我已经在Bash中尝试了它,但是它似乎不起作用:
I have tried it in Bash, but it doesn't seem to work:
for i in `cat file_in.txt`
for j in `cat file_out.txt`; do
java -cp *:ext/*: es.blast2go.prog.B2GAnnotPipe -in $i -out results/$j -prop b2gPipe.properties -v -annot -dat
done
done
推荐答案
paste
可能会有所帮助:
#!/bin/bash
paste file_in.txt file_out.txt | while read if of; do
echo "-in $if -out $of"
done
产量:
-in aphid_splitseq.1.fasta.annot.xml -out aphid_splitseq_1
-in aphid_splitseq.2.fasta.annot.xml -out aphid_splitseq_2
-in aphid_splitseq.3.fasta.annot.xml -out aphid_splitseq_3
-in aphid_splitseq.4.fasta.annot.xml -out aphid_splitseq_4
-in aphid_splitseq.5.fasta.annot.xml -out aphid_splitseq_5
您可以修改它以获得所需的行为.
you can modify this to get the desired behaviour.
