Replace String in Jupyter Notebook File (omc.ipynb)

This command will search for the string "020099" in the file "omc.ipynb" and replace it with "020100". The sed command is a powerful tool for text manipulation on the command line. It can be used to search and replace strings, delete lines, and insert new lines. In this example, the "g" flag at the end of the command indicates that all occurrences of the string "020099" should be replaced. To learn more about the sed command, you can refer to the man page or online resources.
