Remove pattern from filenames
The simplest method is to use the common rename command which is available in most Unices.
rename 's/^mywork_myfile_/mywork_/' *This of course expects you to be on the directory of the files. This will not overwrite files. If you want that, just pass the -f option. Also, take note that there's multiple versions of rename out there which may have different options.
Based on this answer on "Rename all files in "Rename all files in directory from $filename_h to $filename_half?", this can be a way:
for file in mywork_myfile*txtdo mv "$file" "${file/_myfile/}"doneNote that it uses the bash string operations as follows:
$ file="mywork_myfile_XSOP.txt"$ echo ${file/_myfile/}mywork_XSOP.txt
