yapet – text based password manager Synopsis yapet [[-c] | [-h] | [-V]] [[-i] | [-r {rcfile}]] [[-s] | [-S]] [-t {sec}] [filename]Descriptionyapet provides a text user interface for storing passwords and associated information (referred to as password records) in files encrypted on disk. A password record is comprised of a record name, host name, user name,…
yaml_to_db – convert a subset of YAML into fsdb Synopsis yaml_to_db <source.yamlDescriptionConverts a very limited subset of YAML into Fsdb format. The input is YAML-format (not fsdb). The input is parsed as YAML, assuming the file is an array of dictionary entries. We extract the dictionary names and output this as an fsdb table. The…
yad – display GTK+ dialogs in shell scripts Synopsisyad [OPTIONS] DescriptionYAD is a program that will display GTK+ dialogs, and return (either in the return code or on standard output) the users input. This allows you to present information, and ask for information from the user, from all manner of shell scripts. YAD is the…
yacg – Yet Another Configuration Generator Synopsisyacg [OPTIONS] PATH yacg –help|–manual|–version Descriptionyacg reads the given high-level configuration file, carefully validates it and generates ready-to-use (configuration) files. The high-level configuration file can be altered using the –set, –unset and –merge options. It can be inspected using the –dump option. The files can be generated at their…
Yacc – an LALR(1) parser generator Synopsisyacc [ -dgilrtv ] [ -b file_prefix ] [ -p symbol_prefix ] filename DescriptionYacc reads the grammar specification in the file filename and generates an LALR(1) parser for it. The parsers consist of a set of LALR(1) parsing tables and a driver routine written in the C programming language….
yac2ncid – YAC server to NCID server gateway Synopsisyac2ncid [-v] DescriptionYAC2NCID acts as a YAC client, listens to the CID information from a YAC server and sends it to the NCID server. The server then sends the CID information to the NCID clients. It is important to understand that to run YAC server with NCID…
y4munsharp – Unsharp filter for YUV4MPEG2 streams Synopsisy4munsharp [options] Descriptiony4munsharp is an implementation of the GIMP unsharp filter for YUV4MPEG2 streams. The usual 3 parameters for unshap mask processing (radius, amount and threshold) are specified on the command line. By default only the Y’ (luma) component is processed although processing of the CbCr (chroma) may…
y4mtoppm – Convert YUV4MPEG2 stream to PPM images Synopsisy4mtoppm [options] Descriptiony4mtoppm converts a YUV4MPEG2 stream into a sequence of raw PPM images. Output is to stdout (but feel free to have the shell redirect to a file). Input is read from stdin, like all other YUV4MPEG2 filters and tools. YUV4MPEG2 streams contain frames using the…
y4mtopnm – Convert a YUV4MPEG2 stream to PNM images Synopsisy4mtopnm [options] Descriptiony4mtopnm converts a YUV4MPEG2 stream into a sequence of raw PPM, PGM, or PAM images. (Technically, "pnm" comprises the PPM, PGM and PBM formats. PAM is a fourth format, which can effectively contain any of the other three, and more.) Output is to stdout…
y4mscaler – Scale/crop/translate a YUV4MPEG2 stream Synopsisy4mscaler [options] < Y4Mstream > Y4Mstream Descriptiony4mscaler is a general-purpose video scaler which operates on YUV4MPEG2 streams, as produced and consumed by the MJPEGtools such as lav2yuv and mpeg2enc(1). y4mscaler is meant to be used in a pipeline. Thus, input is from stdin, and output is to stdout. The…
y4mdenoise – Motion-compensating YUV4MPEG-frame denoiser Synopsisy4mdenoise [-v verbosity] [-p parallelism] [-r motion-search_radius] [-R color_motion-search_radius] [-t error_tolerance] [-T color_error_tolerance] [-z zero_motion_error_tolerance] [-Z color_zero_motion_error_tolerance] [-m match-count_throttle] [-M match-size_throttle] [-f reference_frames] [-B] [-I interlacing_type] < /dev/stdin > /dev/stdout Descriptiony4mdenoise can be used to remove noise from images in a YUV4MPEG2 stream. This is useful for cleaning old sources…
y4mcolorbars – Create a YUV4MPEG2 stream containing a colorbar test pattern Synopsisy4mcolorbars [options] Descriptiony4mcolorbars creates a YUV4MPEG2 stream consisting entirely of frames containing a colorbar test pattern. The pattern attempts to reproduce the standard SMPTE EG-1-1990 colorbar test signal as faithfully as possible, given the constraints of the Y’CbCr colorspace. Output is to stdout to…
xzmore, lzmore – view xz or lzma compressed (text) files Synopsisxzmore [file…] lzmore [file…] Descriptionxzmore is a filter which allows examination of xz(1) or lzma(1) compressed text files one screenful at a time on a soft-copy terminal. To use a pager other than the default more, set environment variable PAGER to the name of the…
xzless, lzless – view xz or lzma compressed (text) files Synopsisxzless [file…] lzless [file…] Descriptionxzless is a filter that displays text from compressed files to a terminal. It works on files compressed with xz(1) or lzma(1). If no files are given, xzless reads from standard input. xzless uses less(1) to present its output. Unlike xzmore,…
xzgrep – search compressed files for a regular expression Synopsisxzgrep [grep_options] [-e] pattern file… xzegrep … xzfgrep … lzgrep … lzegrep … lzfgrep … Descriptionxzgrep invokes grep(1) on files which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), bzip2(1), lzop(1), or zstd(1). All options specified are passed directly to grep(1). If no file…
