Deleting a Line of Text from the Text Buffer
You can use the db command to delete a specific line in the text buffer. To use this
command, enter db, followed by line number of the line of text you want delete, which is
shown by the lb command. For example, to delete the third line of text in the text buffer,
enter
db 3
at the system prompt.
Enter the
lb command again to view the contents of the buffer. Note that the text that
appeared at line 3 has been deleted.
Inserting a Line of Text into the Text Buffer
You can use the ib command to insert a line of text between two existing lines in the buffer.
To use this command, enter ib, followed by the number of the line where you want the new
text to appear. For example, if you want to add the text, atm_use_mbus=3, between lines 00
and 01 in the buffer, enter
ib 1
at the system prompt. The following screen will be displayed:
01:
Enter the line of text, atm_use_mbus=3.
At the system prompt, enter the
lb command to view the contents of the buffer. If the origi-
nal text buffer looked like this,
00: cmDoDump=1
01: cmInit
the revised text buffer, with the inserted text, will now appear as follows:
00: cmDoDump=1
01: atm_use_mbus=3
02: cmInit
Editing a Line Name of Text in the Text Buffer
You can use the eb command to edit an existing line of text in the buffer. To use this
command, enter
eb, followed by the line number of the text you want to edit. For example, if
you want to edit the text at line 01, enter
eb 1
at the system prompt. The following screen will be displayed:
01:
Enter the text as you want it to appear and press <Enter>.
Enter the
lb command again to list the contents of the text buffer. Note that the buffer now
reflects the edited line of text.
