I have a file name such as follows:
file_name1.pdf.sometext.here
I have a directory of several files in the same format, and I want to edit all the files so that the portion after .pdf is deleted... thus the file would look like this
file_name1.pdf
Using parameter expansion:
$ ls *.pdf*
file_name1.pdf.sometext.here file_name2.pdf.blah file_name3.pdf.sometext
$ for fname in *.pdf*; do mv "$fname" "${fname//.pdf.*/.pdf}"; done
$ ls *.pdf*
file_name1.pdf file_name2.pdf file_name3.pdf
