Delete Line
The Delete Line object deletes lines from a text file.
Note: This object replaces functionality in the Manage Text File Legacy object. For more information, see the Legacy topic.
How it is used
Use the Delete Line object to delete outdated lines of text from a text file.
Configuration
To configure the Delete Line object you need to know the name of the file that you want to delete the line from, the file encoding it uses, and the line numbers of the lines that you want to delete.
Details Tab
 
File
Type the path and name of the file that you want to delete the text from, or click the ellipsis button (...) and browse for it.
File encoding
Click the ellipsis button (...) and select the format that the file is encoded in from the File encoding drop-down list. Verify that you select the correct encoding format: if the file uses a different encoding format, the object fails.
Line numbers
Type the line numbers of the text that you want to delete from the file that you specified.
To specify a range of lines, use a hyphen: 1-3. This deletes lines 1 to 3.
To specify specific lines, use a comma: 5,7,9. This deletes lines 5, 7, and 9.
Combine the range and specific lines: 1-3,5,7,9. This deletes lines 1 to 3, and lines 5, 7, and 9.
To specify from a specific line to the last line of the file, type the line number, hyphen, and END: 4-END. This deletes lines 4 to the last line of the file.
To specify from a specific line to a line relative to the last line of the file, type the line number, hyphen, the less-than sign, and the line number relative to the end line: 4-END<3. If the file has 20 lines, this deletes lines 4 to 17 from the file. <3 represents the third line from the end.
To specify the last number of lines, type LASTLINES, colon, and the last number of lines that you want to delete: LASTLINES:10. This deletes the last 10 lines of the file.
Combine different types of operations: 1-5, 8, 10-END<20, LASTLINES:10. This deletes lines 1 to 5, line 8, line 10 to the 20th line from the end, and the last 10 lines. Do not overlap lines or line ranges when combining operations. For example, 5-END, LASTLINES:10 fails because the 5-END operation already deletes to the end, so the LASTLINES:10 operation cannot succeed because the lines are already deleted, and the object fails.
Note: Do not specify lines numbers that do not exist in the file, and do not specify a line number more than once, or the object fails.
