create unique temporary files
#!/bin/bash
for f in 1 2 3
do
file=$(mktemp)
echo "Writing file $file"
echo "My Contents" >> $file
done
Using a Name Template
Using the -t
option with mktemp allows us to define a prefix for the temporary files.
#!/bin/bash
for f in 1 2 3
do
file=$(mktemp -t file_${f})
echo "Writing file $file"
echo "My Contents" >> $file
done
Note that in this case, the ${f} is not required to use -t. It’s to get our loop variable into our file name template.
Using mktemp for a Temporary Directory
create a temporary directory (using -d
)
#!/bin/bash
dir=$(mktemp -d)
for f in 1 2 3
do
file=file_$f.txt
echo "Writing file $file to dir $dir"
echo "My Contents" >> "$dir/$file"
done
...
rm -r $dir # remove temporary dir
