Question

I m writing a bash script that will (hopefully) redirect to a file whose name is generated dynamically, based on the the first argument given to the script, prepended to the some string. The name of the script is ./buildcsvs.

Here s what the code looks like now, without the dynamic file names

#!/bin/bash
mdb-export 2011ROXBURY.mdb TEAM > team.csv

在这里,我喜欢这样说来。

./buildcsvs roxbury

产出

roxburyteam.csv

“1美元”是文字的首批动力,档案名称被像一类的东西所定义。

"%steam" % $1

你们是否有任何想法? 谢谢。

Answer 1

1美元与“team.csv”。

#!/bin/bash
mdb-export 2011ROXBURY.mdb TEAM > "${1}team.csv"

如果他们不向书写人提出论据,将写上“team.csv”。

Answer 2

你可以通过<条码>1或其他类似内容提及一种立场论点。我写了以下微薄的测试文字,以证明如何做:

$ cat buildcsv 
#!/bin/bash
echo foo > $1.csv
$ ./buildcsv roxbury
$ ./buildcsv sarnold
$ ls -l roxbury.csv sarnold.csv 
-rw-rw-r-- 1 sarnold sarnold 4 May 12 17:32 roxbury.csv
-rw-rw-r-- 1 sarnold sarnold 4 May 12 17:32 sarnold.csv

Try replacing team.csv with $1.csv.

请注意,未经争辩即可操作该书状,然后制作 empt/em>。编号.csv。如果你想处理,你必须计算使用<代码>的编号<#>/code>的论点。我也赞扬:

$ cat buildcsv 
#!/bin/bash
(( $# != 1 )) && echo Need an argument && exit 1
echo foo > $1.csv
