This is actually a pretty common thing to run into in a Linux file system. It is especially prevalent in the files that are moved from another operating system (Usually Windows). So if you get files that need to have a space or a character removed, the below snipped is a very simple, and handy way to fix this issue.
file – 2.txt
So, from here we want to rename the file “file 1.txt” to “file_1.txt”. This would be done as follows:
rename ‘s/ /_/g’ file 1.txt
This will remove any spaces in the file-name listed. If you want to do all the files in a directory:
rename ‘s/ /_/g’ *
Here is an example output if we run it on all the files in the directory (as seen above):
Note: If you are new to Linux; and you haven’t heard of the “sed” command, that is the syntax used in the command. If you get comfortable with this, then you can easily learn sed, which is a great tool to have on the command line.
