Renaming files removing some unwanted extension

for i in *ext; do mv $i ${i%.ext}; done
For those files in current folder that would be shown in `ls *ext`, for some extension ext, move/rename that file removing the .ext suffix from the file name. It uses Bash's parameter substitution, as seen in http://tldp.org/LDP/abs/html/parameter-substitution.html#PCTPATREF (for analog use in prefix, see http://tldp.org/LDP/abs/html/parameter-substitution.html#PSOREX2 )

What Others Think

for i in *.ext; do mv $i ${i%.ext}; done - no need for `ls *ext`, but need for point before *.ext if you dont want to rename the files mytext for instance. - no need for star in parameter substitution Theses two corrections are similar as the example of the first link you gave : "Example 10-11. Renaming file extensions"

-1 for parsing ls, which you should never do. Using a for-loop is far cleaner.
