[Bash] Batch renaming files
Despite (or perhaps because of) the fact I’ve been using Linux for more than a decade, I’ve done a great job of avoiding sed. I have done my best to make up for it in the recent past by learning how to at least find and replace, either within a file or in a filename. Here is how you batch rename files using sed in a Bash shell.
To rename all *.txt files in a directory (in this case to replace any spaces with _.
for file in *.txt; do mv "$file" "$(echo $file | sed -e 's/ /_/g')"; done
for file in *.txt
For each text (.txt) file in this directory.
do mv "$file"
Move the file from it’s current name to
"$(echo $file | sed -e 's/ /_/g')"
this. In this second part, we echo the name of the file and pipe the name into sed. The syntax for find and replace in sed is:
sed -e 's/foo/bar/g where foo is the old string and bar is the new string. You echo the file name, and simply replace the ” ” with “_”.
I sincerely hope this is useful to somebody, somewhere.
