GMT_SHELL_FUNCTIONS.SH(1gmt) Generic Mapping Tools GMT_SHELL_FUNCTIONS.SH(1gmt)
NAME
gmt_shell_functions.sh - Practical functions to be used in GMT bourne shell scripts
SYNOPSIS
gmt_init_tmpdir
gmt_remove_tmpdir
gmt_clean_up [prefix]
gmt_message message
gmt_abort message
gmt_nrecords file(s)
gmt_nfields string
gmt_get_field string
gmt_get_region file(s) [options]

DESCRIPTION
gmt_shell_functions.sh provides a set of functions to Bourne (again) shell scripts in support of GMT. The calling shell script should
include the following line, before the functions can be used:
. gmt_shell_functions.sh
Once included in a shell script, gmt_shell_functions.sh allows GMT users to do some scripting more easily than otherwise. The functions
made available are:
gmt_init_tmpdir
Creates a temporary directory in /tmp or (when defined) in the directory specified by the environment variable TMPDIR. The name of
the temporary directory is returned as environment variable GMT_TMPDIR. This function also causes GMT to run in `isolation mode',
i.e. all temporary files will be created in GMT_TMPDIR and the .gmtdefaults file will not be adjusted.
gmt_remove_tmpdir
Removes the temporary directory and unsets the GMT_TMPDIR environment variable.
gmt_cleanup
Remove all files and directories in which the current process number is part of the file name. If the optional prefix is given then
we also delete all files and directories that begins with the given prefix.
gmt_message
Send a message to standard error.
gmt_abort
Send a message to standard error and exit the shell.
gmt_nrecords
Returns the total number of lines in file(s)
gmt_nfields
Returns the number of fields or words in string
gmt_get_field
Returns the given field in a string. Must pass string between double quotes to preserve it as one item.
gmt_get_region
Returns the region in the form w/e/s/n based on the data in table file(s). Optionally add -Idx/dy to round off the answer.
gmt_get_gridregion
Returns the region in the form w/e/s/n based on the header of a grid file. Optionally add -Idx/dy to round off the answer.
gmt_map_width
Expects the user to give the desired -R -J settings and returns the map width in the current measurement unit.
gmt_map_height
Expects the user to give the desired -R -J settings and returns the map height in the current measurement unit.
gmt_set_psfile
Create the output PostScript file name based on the base name of a given file (usually the script name $0).
gmt_set_framename
Returns a lexically ordered filename stem (i.e., no extension) given the file prefix and the current frame number, using a width of
6 for the integer including leading zeros. Useful when creating animations and lexically sorted filenames are required.
gmt_set_framenext
Accepts the current frame integer counter and returns the next integer counter.
NOTES
1. These functions only work in the bourne shell (sh) and their derivatives (like ash, bash, ksh and zsh). These functions do not work in
the C shell (csh) or their derivatives (like tcsh), and cannot be used in DOS batch scripts either.
2. gmt_shell_functions.sh were first introduced in GMT version 4.2.2 and have since been regularly expanded with other practical scripting
short-cuts. If you want to suggest other functions, please do so by mailing to the GMT mailing list: gmt-help@lists.hawaii.edu.
