Recently I came across a need to create a Linux shell script to run a PostgreSQL SQL query, export it in CSV Format and send it attached to an email. The following is a self-explanatory Linux shell script outlining the process.
#!/bin/bash # Export PATH in case SENDMAIL is not found by the script export PATH=/usr/sbin:/usr/bin # EXPORT POSTGRES SQL COMMAND AS CSV # Adjust the Select SQL command to your liking # Note: You may need to define the path to export.csv file ./psql -d DBNAME -t -A -F"," -c "SELECT * FROM TABLE" > export.csv # SEND AN EMAIL # Note: You may need to define the path to export.csv file on the bottom line ( echo "to: firstname.lastname@example.org" echo "from: POSTGRESQL SERVER <email@example.com>" echo "Subject: PostgreSQL Export as of $(date +%F)" echo "mime-version: 1.0" echo "content-type: multipart/related; boundary=messageBoundary" echo echo "--messageBoundary" echo "content-type: text/plain" echo echo "Please find the export in CSV format attached to this email." echo "Created: $(date)." echo echo "--messageBoundary" echo "content-type: text; name=export.csv" echo "content-transfer-encoding: base64" echo openssl base64 < export.csv) | sendmail -t -i
I hope this helped someone.
