[英]Linux Shell Script For Each File in a Directory Grab the filename and execute a program
Scenario : 场景:
A folder in Linux system. Linux系统中的一个文件夹。 I want to loop through every .xls file in a folder.
我想遍历文件夹中的每个.xls文件。
This folder typically consists of various folders, various filetypes (.sh, .pl,.csv,...). 此文件夹通常包含各种文件夹,各种文件类型(.sh,.pl,.csv,...)。
All I want to do is loop through all files in the root and execute a program only on .xls files. 我想要做的就是循环遍历根目录中的所有文件,并仅在.xls文件上执行程序。
Edit : 编辑:
The problem is the program I have to execute is 'xls2csv' to convert from .xls to .csv format. 问题是我必须执行的程序是'xls2csv'才能从.xls转换为.csv格式。 So, for each .xls file I have to grab the filename and append it to .csv.
因此,对于每个.xls文件,我必须获取文件名并将其附加到.csv。
For instance, I have a test.xls file and the arguments fro xls2csv are : xls2csv test.xls test.csv
例如,我有一个test.xls文件,xls2csv的参数是:
xls2csv test.xls test.csv
Did I make sense? 我有道理吗?
庆典:
for f in *.xls ; do xls2csv "$f" "${f%.xls}.csv" ; done
for i in *.xls ; do
[[ -f "$i" ]] || continue
xls2csv "$i" "${i%.xls}.csv"
done
The first line in the do
checks if the "matching" file really exists, because in case nothing matches in your for
, the do
will be executed with "*.xls" as $i
. do
的第一行检查“匹配”文件是否确实存在,因为如果你的for
没有匹配,则do
将以“* .xls”作为$i
。 This could be horrible for your xls2csv
. 这对你的
xls2csv
可能很糟糕。
Look at the find command. 查看find命令。
What you are looking for is something like 你要找的是什么
find . -name "*.xls" -type f -exec program
Post edit 发布编辑
find . -name "*.xls" -type f -exec xls2csv '{}' '{}'.csv;
will execute xls2csv file.xls file.xls.csv
将执行
xls2csv file.xls file.xls.csv
Closer to what you want. 更接近你想要的。
find . -type f -name "*.xls" -printf "xls2csv %p %p.csv\n" | bash
bash 4 (recursive) bash 4(递归)
shopt -s globstar
for xls in /path/**/*.xls
do
xls2csv "$xls" "${xls%.xls}.csv"
done
