Need help in splitting filename and folder path using shell script

I am a novice in shell scripting. I need to split this following file structure as filename separate and folder path separate. In the filename, I don't need _ABF1_6, as it is not part of the filename. Also this _ABF1_6 changes from file path to path and is not the same for all filepaths. So this needs to be considered as regular expression..beginning with _ABF1. Please help!!

Sample filepath:

/EBF/DirectiveFiles/data_report_PD_import_script_ABF1_6

Output required:

Folder path: /EBF/DirectiveFiles/ 
Filename: data_report_PD_import_script

You can use shell parameter expansion for this. :

user> p=/EBF/DirectiveFiles/data_report_PD_import_script_ABF1_6 
user> echo ${p%/*}
/EBF/DirectiveFiles
user> f=${p##/}
user> echo ${f%_ABF1}
data_report_PD_import_script

[Here][1] is a link to the bash documentation on this.

Or with read and GNU sed (not as portable as the above):

read dir file < <(sed -r 's:(.*)/(.*)_ABF1.*:"\1" "\2":' <<<"$p")
echo $dir $file

Output:

"/EBF/DirectiveFiles" "data_report_PD_import_script"

Linux has special utilities for this reason, basename and dirname:

$ basename /EBF/DirectiveFiles/data_report_PD_import_script_ABF1_6
data_report_PD_import_script_ABF1_6
$ dirname /EBF/DirectiveFiles/data_report_PD_import_script_ABF1_6
/EBF/DirectiveFiles

UNIX doesn't have "folders", it has "directories".

$ cat file
/ECMS/EDEV/ClassicClient/Forms/DirectiveFiles/data_report_PD_import_script_rev1_46_2_16

$ sed -r 's/(.*\/)(.*)_rev1.*/Directory: \1\nFilename: \2/' file
Directory: /ECMS/EDEV/ClassicClient/Forms/DirectiveFiles/
Filename: data_report_PD_import_script

or with GNU awk (for gensub()) if you prefer:

$ gawk '{print gensub(/(.*\/)(.*)_rev1.*/,"Directory: \\1\nFilename: \\2","")}' file
Directory: /ECMS/EDEV/ClassicClient/Forms/DirectiveFiles/
Filename: data_report_PD_import_script
