"top -c" doesn't work from under cron

[Vitaly Karasik_1]

I want to save "top -c" output into a file for parsing it.

I use this command:
/usr/bin/top -bc -n1 >/tmp/top.out

This works nice from a command line, but when I run it under cron, "top" output is cutted to 80 symbols, so I don't see command line for each process.
I guess it is related to the fact, that it is no terminal attached when script is running under cron. But how to fix this?

export COLUMNS=127

You can do like this

#export UNIX95=1;top -h -n5 -d1 -f

It'll run from crontab also.

[root@linux1 ~]# export UNIX95=1;top -h -n5 -d1 -f /tmp/top.out
top: procps version 3.2.3
usage: top -hv | -bcisS -d delay -n iterations [-u user | -U user] -p pid [,pid ...]

youcan try like this

export UNIX95;top -d 1 -n 2

If it's just for one instance of the command, you can use set the variable in the same command, instead of exporting the variable, i.e.

UNIX95=1 top -d1 -n2

This sets the variable for that single command.
