How to rename files in bulk with commands

I believe that everyone, whether it is a programmer or a white-collar worker in other industries, will encounter a need when using a computer to work, that is, to rename a large number of files with a certain number of regular names.

For programmers, in a Linux environment, we can use some command-line tools to accomplish this.

For example, there are log files as follows:

root@linux:~/test# ls test-*

test-10.log test-1.log test-2.log test-3.log test-4.log test-5.log test-6.log test-7.log test-8.log test-9.log

rename -v 's/\.log$/\.txt/' test*.log

The -v parameter is used to print the name of the file that was successfully renamed, which is actually the process record of the output processing, which can be used to verify whether the renaming process meets the requirements. 's/\.log$/\.txt/'is a perl regular expression, which means that a string is filled with .The part at the end of the log is replaced with .txt。

Or it can be usedmvcommands in conjunction with a for loop

for name in `ls test*.log`; do mv $name $.txt ; done

In the loop body, we use the $ string treatment, which means that the same as the . is deleted from the end of the namelog matches the smallest part and returns the remainder; After that, add .txt suffix. By doing this, we can change the filename suffix from .log totxt。Finally, we use the mv command to actually rename the file.

If we come across these files like this:

root@linux:~/test# ls test-*

test-10-0eb22520 test-2-09e36680 test-4-0b189764 test-6-0c4bd416 test-8-0d7ebb96
test-1-0949b5c6 test-3-0a7d3e36 test-5-0bb2609c test-7-0ce5454c test-9-0e189874

for file in `ls test-*`do

newname=$(echo $file | sed 's/.\$//')
mv $file $newname
done

For those who use Windows to work, you can also use the command tool to rename in batches. For example, there are many jpeg files in the test directory under the C drive

The filename suffix needs to be renamed to jpg, and we can open the cmd window,

cd \

cd test
ren *.jpeg *.jpg

In the cmd window, we can use the command help ren or ren ?to see usage tips.
