- You want to trace program execution on Solaris?
- You want to perform network tracing on Solaris?
- Perform a text dump of a binary file - or see ascii codes, etc?
- Generate some random data?
- List directory contents in 3 columns?
- Loop through a list of files and perform actions on them?
- Check for values in vars?
- Detach a process without it dying.
- Perform arithmetic in shell.

- System process debug (solaris) all exec/reads
truss -xall -vall -rall -t'read' -p PID - Network trace connection from hostname (solaris)
snoop -x0 src hostname - Optical dump of a file, useful for seeing control chars, etc and lines with no newline.
od -c filename - Generate 512 bytes of random data, cat -ve escapes control chars.
dd bs=1 count=512 if=/dev/urandom | cat -ve - list directory contents, display in 3 columns.
ls | paste - - - - Loop through all files and perform an action on it.
for na in * ; do echo $na ; done - Check for values in vars.
[[ $(echo $var | grep -ic "pattern") -eq 0 ]] & You could also go for "-eq 1" - does contain or -ne 0 for same, etc. Plus you could use || for "or" either in place of "&&" or after this block - same as if .. then "positive" else "negative" fi. - Detach a process without it dying.
disown [%1] nohup command > /tmp/logfile.log 2>&1& If you start a process with nohop (ignore the hup signal), it will not exist (usually) when your shell is exited. This can now be simulated on solaris, by backgrounding a process (with ctrl Z and bg) then typing disown. jobs command will show all backgrounded jobs. Ideally start commands like this, to avoid the shell exit problem: - Perform arithmetic in shell.
bc -l Binary Calculator in long format - for float, etc. Can also be automated like this, to convert between decimal and hex: i=0; while ((i<20)) ; do echo -n "$i: "; echo "base=10;obase=16;$i" | bc; ((i++)); done | paste - - - -
