Terrance Dudley appeals the district court’s 1 dismissal of his pro se 42 U.S.C. § 1988 complaint for failure to comply with a court order, pursuant to Federal Rule of Civil Procedure 41(b). We grant Dudley leave to appeal in forma pauperis, leaving fee collection to the district court. See Henderson v. Norris, 129 F.3d 481, 484-85 (8th Cir. 1997) (per curiam). We conclude that the district court did not abuse its discretion. See Smith v. Gold Dust Casino, 526 F.3d 402, 404-05 (8th Cir. 2008). Despite warnings that dismissal could result from his failure to do so, Dudley did not follow the magistrate judge’s order to file an amended complaint. See In re Reid, 197 F.3d 318, 320 (8th Cir. 1999). We note the dismissal was without prejudice, which leaves Dudley free to refile his claims. Accordingly, we affirm. See 8th Cir. R. 47A(a).
