# epost(1)

upload a batch of NCBI Entrez record identifiers

## NAME

epost - upload a batch of NCBI Entrez record identifiers

## SYNOPSIS

**epost** \[**-help**\] \[**-db** *name*\] \[**-id** *ID(s)*\] \[**-format** *fmt*\] \[**-input** *filename*\]

## DESCRIPTION

**epost** uploads a batch of record identifiers (textual accessions or numeric UIDs) to Entrez history servers for processing by other Entrez Direct commands. By default, it reads these identifiers from standard input.

## OPTIONS

- **-help**

  Print usage information.

- **-db** *name*

  Indicate that the identifiers are from the specified database.

- **-id** *ID(s)*

  Specify identifiers directly.

- **-format** *fmt*

  **uid** or **acc**(ession).

- **-input** *filename*

  Read from *filename* instead of standard input (which is then free to receive pipeline state from other Entrez Direct commands).
