Solaris

I have a script name as psin_install_i3fp.sh

I need to run this script like ./psin_install_i3fp.sh step2

What this step2 represents?



my script contains data:
#!/bin/ksh

mkdir logs >> /dev/null 2>&1

./infra/bin/psin_stop_ba.sh
mv ./psin_start_ba.sh ./infra/bin/psin_start_ba_moved.sh >> /dev/null 2>&1
mv ./psin_stop_ba.sh ./infra/bin/psin_stop_ba_moved.sh >> /dev/null 2>&1

sleep 5

./psin_start_i3.sh

if [ -f distribution/psin_cli_UNIX.zip ] ; then
./infra/utils/unzip -o -q distribution/psin_cli_UNIX.zip > logs/infra.extract.cli.out 2>&1
fi




and also tell me the below line represnts:

mv ./psin_start_ba.sh ./infra/bin/psin_start_ba_moved.sh >> /dev/null 2>&1

The step2 represents nothing, as it is not parsed anywhere in the script you provided.


The command you asked for moves a file (see man mv for details), any output from that command is redirected to /dev/null (unix' black hole). Actually the redirection done with ,,>>'' is meaningless, single ,,>'' would suffice and do exactly the same in this case.

Its a bad coding.. shouldn't have "./" in your codes, use a full path instead and also assign a variable name so that it wont be messy
