Correct command question for trimming to a fixed length

[FaehlingT]

Dear Team,

thanks for the nice tool you have designed. I have a quite specific question and i don't think I could find this in the documentation... Is it possible to trim the reads (single-end read) to a fixed length without any regard to quality (so only the first X bases are retained), and what command can I use for Illumina fastq files for this? Thanks for your help and best wishes, t221f
