UNIX-User's Cheater Table

This table lists commands available in the CL-Environment, the classical OS/400-Shell, so to say. These do not apply to QSH or PASE, that are UNIX-like environments within OS/400.

UNIX Command	OS/400 Equivalent	Remarks
Files and File System
cat	cpyf	Since OS/400 has no concept of stdin/stdout, these functions of cat don't apply here.
cd	chgcurlib
chmod	chgaut, grtobjaut, rvkobjaut
chown, chgrp	chgobjown
cp	crtdupobj
dump, tar c	sav(lib|obj| )
ls	wrklib wrkobj	Shows a scrollable list of selected objects, helps in modifying access rights.
mv	rnmobj movobj
restore, tar [x|t]	rst(lib|obj| ), dspsavf, dsptap
test -f	chkobj chkifsobj
vi	strseu for source physical files, edtf for stream files, strdfu option(5) for database files.	See Filesystems and Files on the AS/400 for details. See IBM HTTP-Server for AS/400 Configuration for specialised command regarding web server config.
Memory and Processes
free	wrkshrpool	This is for displaying the amount of built-in RAM.
crontab -e at (scheduler)	wrkjobscde sbmjob wrkjobq qbatch
ps aux, ps -edf, top	wrkactjob
Disk and I/O
df	strsst	Access to precise disk space stats is available within system service tools only.
fsck	rclstg	System needs to be in restricted mode.
iostat -x	wrkdsksts
vmstat	dspsyssts	Choose view option 3 after pressing F19.
Networking
ping, aping	ping	Surprise, command has same name! The latter is for SNA APPN.
netstat, wrkappnsts	netstat	Surprise, command has same name! The latter is for SNA APPN.
Development
cc	crtcmod	Create Object File from C-Source.
ld	crtpgm	Create runnable Program from Object File.
make		No real equivalent. Might be partly substituted with REXX code. There might be something related to a static makefile generator in the QUSRTOOLS library.
configure		No equivalent to GNU autoconf. Possible workaround: Manually tailored, static, universal config.in for each OS-Release (Compiler Version) based on existing documentation and/or manual tests.
Other Topics
lpq	wrkoutq	Displays all configured printer queues and count of entries.
mailx	dspmsg, snddst	Cron and at send mail if there was output. OS/400 sends messages and generates printer output (spooled file). Sending (SMTP) mail from the command line utilises a completely different facility.
mt	dsptap
mysql, isql	strsql	Not limited to mysql that is more like a placeholder for any command line client accessing a database for entering SQL queries directly.

The table will be expanded over time.
