|
#debugme logger "Sorting the database"
|
|
#database_sort
|
|
#debugme logger "Finished sorting the database, exit code $?"

|
|
# (script file or keyboard)
|
|
# * print everything before any ( substitution and expansion, …) is applied
|
|
set -v
|
|
|
|
# * print everything as if it were executed, after substitution and expansion is applied
|
|
# * indicate the depth-level of the subshell (by default by prefixing a + (plus) sign to
|
|
# the displayed command)
|
|
# * indicate the recognized words after word splitting by marking them like 'x y'
|
|
# * in shell version 4.1, this debug output can be printed to a configurable file
|
|
#descriptor, rather than sdtout by setting the BASH_XTRACEFD variable.
