Sets the read/write pointer to the specified position in the file.
/fseek <name> <position>
The following switches can also be used to move the file pointer:
| Switch | Meaning |
| l | /fseek -l <name> <linenumber>. Moves the pointer to the begin of the specified line. |
| n | /fseek -n <name>. Moves the pointer to the begin of the next line. |
| w | /fseek -w <name> <wildcard>. Moves the pointer to the next occurrence of a string matching this wildcard from the current position of the pointer (see example below). |
| r | /fseek -r <name> <regex>. Moves the pointer to the next occurrence of a string matching the regex. |
Note that mIRC will internally set the pointer to byte 0 and scan for <linenumber> - 1 CR/LF combinations when using the -l switch.
Example
Let's imagine with have the following file "moo.txt" in our mircdir:
This is my first line containing moo! This is just a senseless text file. mooooo thats the end. moo?
We have opened this file using /fopen moo moo.txt
/fseek -l moo 2
This example would set the position of the pointer to the begin of the second line (infront of This is just a senseless text file.).
/fseek -n moo
This example would set the pointer to the begin of the next line (infront of 'mooooo').
/fseek -w moo *the*
This example would move the pointer to the beginning of the next line matching *the* (that is line 4 in our example). In case the wildcard text matches the current line and the pointer did not pass the wildcard text yet, the pointer will stay at the current position.
