在 bash 脚本中将 *.txt.csv 文件重命名为 .csv

Question

I have.txt files, which I am taking as $item and then I am changing the encoding with

iconv -f $currentEncoding -t $targetEncoding "$item" -o "$item.tmp"

then I am saving it again to txt file using

 mv "$item.tmp" "$item.txt";

next I am trimming a few things in txt file and saving it as a csv file with

 tr -d '"' < "$item.txt" > "$item.csv";

but eventually my files are getting stored with extension "*.txt.csv" - I want them to be just.csv - can anyone help me please what I am doing wrong or what could I change. Thanks

Answer 1

From what I understand, your $item already has.txt in the value. So, if you list your files after each command, you should see intermediate files like

xyz.txt.tmp
xyz.txt.txt
xyz.txt.csv

So, when you set the item variable, just do ${item%%.*} as shown below and it should work as expected.

item=xyz.txt               
item="${item%%.*}"    
echo $item        
xyz

Answer 2

Run:

for f in *.txt.csv; do mv $f ${f/.txt./.}; done

If the variable $f contains the string item.txt.csv , the expression ${f/.txt./.} removes .txt from the file name and gives only the string item.csv .

Caution: if one of the filenames contain spaces, the for statement will not work as expected.
