I am not an expert of shell scripting, but I can do some simple things. Now, I read a script written by others and I need some help from the experts of this forum.
Please help me to understand what is going on in this cycle:
In particular, I do not understand this synax: [[...]] && \ export... ||,
where the || operand is used after the export command. It rise by me the question if the export command return any Boolean value?
i have this program in bash shell:
#!/bin/bash
array=(20 20 20 20 20)
i=0
j=0
awk '/%/ {print $3}' try.txt|
while (read s)
arr=$s
i=`expr $i + 1`
echo "$i"
end
how can i convert this into c shell? (1 Reply)

export
asadmin-export(1AS) User Commands asadmin-export(1AS)NAME
asadmin-export, export - marks a variable name for automatic export to the environment of subsequent commands in multimode
SYNOPSIS
export [ name=value [ name=value]*]
Marks a variable name for automatic export to the environment of subsequent commands. All subsequent commands use the variable name values
as specified; unless you unset them or exit multimode. If only the variable name is specified, the current value of that variable name is
displayed. If the export command is used without any arguments, a list of all the exported variables and their values is displayed.
Exported shell environment variables set prior to invoking the asadmin utility are imported automatically and set as exported variables
within asadmin. Unexported environment variables cannot be read by the asadmin utility.
OPERANDS
name=value variable name and value for automatic export to the environment to be used by subsequent commands.
Example 1: Using export to list the environment variables
asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password
asadmin> export AS_ADMIN_PREFIX=server1.jms-service
asadmin> export //to list the environment variables that are set
AS_ADMIN_HOST=bluestar
AS_ADMIN_PORT=8000
AS_ADMIN_USER=admin
AS_ADMIN_PASSWORD=********
AS_ADMIN_PREFIX=server1.jms-service
Where: the export command lists the environment variables that are set. In this case, the environment variables have been set to: the host
is bluestar, the port is 8000, the administrator user is admin with an associated password, and the prefix is server1.jms-service.
EXIT STATUS
0 command executed successfully
1 error in executing the command
