v With -T, timestamps are printed also in comment form. (This can be used to
produce files suitable for loading with history -L or source -h.)
v With -r, the order of printing is most recent first rather than oldest first.
v With -S, history saves the history list to filename. If the first word of the savehist
shell variable is set to a number, at most that many lines are saved. If the
second word of savehist is set to merge, the history list is merged with the
existing history file instead of replacing it (if there is one) and sorted by time
stamp. Merging is intended for an environment like the X Window System with
several shells in simultaneous use. Currently it only succeeds when the shells
quit one after another.
v With -L, the shell appends filename, which is presumably a history list saved by
the -S option or the savehist mechanism, to the history list. -M is like -L, but the
contents of filename are merged into the history list and sorted by timestamp. In
either case, histfile is used if filename is not given and ~/.history is used if
histfile is unset. history -L is exactly like source -h except that it does not
require a filename.
v With -c, clears the history list.
tcsh login shells do the equivalent of history -L on startup and, if savehist is set,
history -S before exiting. Because only ~/.tcshrc is normally sourced before
~/.history, histfile should be set in ~/.tcshrc rather than ~/.login. If histlit is set,
the first form (history [-hTr] [n]) and second form (history -S|-L|-M [filename]) print
and save the literal (unexpanded) form of the history list.
iconv — Convert characters from one codeset to another
Format
Description
iconv [–sc] –f oldset –t newset [file ...]
iconv –l[–v]
File Tag Specific Options:
iconv [–F] [–M] [–T]
iconv converts characters in file (or from stdin if no file is specified) from one code
page set to another. The converted text is written to stdout. See z/OS XL C/C++
Programming Guide for more information about the code sets supported for this
command.
If the input contains a character that is not valid in the source code set, iconv
replaces it with the byte 0xff and continues, unless the –c option is specified.
history
If the input contains a character that is not valid in the destination code set,
behavior depends on the system’s iconv() function. See z/OS XL C/C++ Run-Time
Library Reference for more information about the character used for converting
incorrect characters.
Also, z/OS XL C/C++ Programming Guide has a list of code pages supported by
the z/OS shell.
