I would like to print a file in cat << EOF>. e.g.
$cat file
ad3
c43
34e
se3
we3
My script is:
$cat run.sh
cat << EOF > test.sh
#!/bin/bash
some commands
cat file #I would like to print the content of the file here
some commands
EOF
I can't able to print as desire with ./run.sh
Desire output
$cat test.sh
#!/bin/bash
some commands
ad3
c43
34e
se3
we3
some commands
CodePudding user response:
You could use a compound command:
{ cat << EOF ; cat file ; cat << EOF2; } > test.sh
> start
> EOF
> more
> EOF2
That gives:
start
ad3
c43
34e
se3
we3
more
CodePudding user response:
You could use backticks, or write the file in chunks:
#!/bin/bash
cat <<OMG >zfile
ad3
c43
34e
se3
we3
OMG
# Method1 : backticks
cat << EOF > test.sh
#!/bin/bash
some commands1
`cat zfile`
some commands2
EOF
# Method2: append
cat << EOF1 > test2.sh
#!/bin/bash
some commands1
EOF1
cat zfile >> test2.sh
cat << EOF2 >> test2.sh
some commands2
EOF2

I think you are searching for something like that?
cat > test.sh <<EOF
#!/bin/bash
some commands
ad3
c43
34e
se3
we3
some commands
EOF
