Lakeith Amir-Sharif moves this court for authorization to proceed in forma pau-peris (IFP) on appeal following the district court’s dismissal of his 42 U.S.C. § 1983 suit. A movant who seeks authorization to proceed IFP on appeal must demonstrate that he is a pauper and that he will raise a nonfrivolous issue on appeal. Carson v. Polley, 689 F.2d 562, 586 (5th Cir. 1982).

In his motion and brief to this court, Amir-Sharif argues that he was denied his rights in connection with a prison disciplinary hearing. Amir-Sharif does not address, and has thus abandoned, the threshold issue whether the district court erred by determining that his suit should *277 be dismissed for want of exhaustion. See Yohey v. Collins, 985 F.2d 222, 225 (5th Cir. 1993). Indeed, Amir-Sharifs failure to identify an error in the district court’s analysis has the same effect as if he had not appealed the judgment. See Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987).

Amir-Sharif has not shown that he will raise a nonfrivolous issue on appeal. See Carson, 689 F.2d at 586. To the contrary, our review of Amir-Sharifs filings with this court shows that this appeal is frivolous. Consequently, Amir-Sharifs motion to proceed IFP on appeal is denied, and this appeal is dismissed as frivolous. See 5th Cir. R. 42.2.

Anir-Sharif has filed other frivolous appeals with this court, as well as frivolous actions in other courts, and we previously warned him that he would likely be sanctioned if he continued to file merit-less pleadings. Amir-Sharif did not heed this warning. We now order Amir-Sharif to pay $455 as a sanction to the clerk of this court. Amir-Sharif is barred from filing any pleading in this court or in any court subject to this court’s jurisdiction until the total amount of the sanction imposed on him is paid in full. Amir-Sharif is also warned that any future meritless filings in this court or any court subject to this court’s jurisdiction will subject him to additional sanctions, as will the failure to withdraw any pending matters that are frivolous.

IFP DENIED; APPEAL DISMISSED; SANCTION IMPOSED; SANCTION WARNING ISSUED.
