Removing date from the filename

Question

I am working on a tool which accepts linux commands. I have files coming from differnt sources and i want to remove date from the file and tool supports '%F' ie absolute file name only.

%F is /Dir1/Subdir/ABC_20190101_PQR.csv
What I want is /Dir1/Subdir/ABC_PQR.csv

kindly help.

I tried some commands but none worked

I want /Dir1/Subdir/ABC_PQR.csv

mv %F {%F//_{0-9}//_{}}

Answer 1

Is this OK?

echo ${text} | sed -r 's/(.*)(_[[:digit:]]*_)(.*)/\1_\3/'

Example:

text="/Dir1/Subdir/ABC_20190101_PQR.csv"
echo ${text} | sed -r 's/(.*)(_[[:digit:]]*_)(.*)/\1_\3/'
/Dir1/Subdir/ABC_PQR.csv

This uses BASH.
