do anything with the last created (touched, accessed) file in the current dir

This command will display the file, but you can change 'cat' to anything else (type 'n' when prompted to cancel the command or anything else to proceed). . Some hints for newbies: type unset bar to make 'bar' function annihilated. For permanent usage you can put this (bar) function in your .bashrc (for bash) or in .profile (for sh). With: . ~/.bashrc you can get all new inserted functions in .bashrc (so the function 'bar' or whatever name you choose) immediately available. Show Sample Output

Read curl output line by line in a while loop

This command will take the output of curl and read it line by line, skipping a step in downloading the file then parsing it. You can then parse each line, or only print the lines that contain certain works using if statements, or whatever you can come up with. Or you can change IFS and use it to parse based on separators other than newline.

Get just LAN IP without all the extra stuff

I just needed to store the LAN IP (for ipv4) in a variable for a specific task in a bash script. I figured I'd share. I sent it to a variable with VAR=$(stuff) and used it later on. I put the exit 0 in the if statement to make it so that it breaks if there are more than one IPv4 addresses assigned. I only wanted the first one. Edit: Bear in mind, my network mask is a double digit number so if you have a smaller nw mask you'd need to edit the sed statement. Show Sample Output

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

output length of longest line

If your wc does not have the -L option, you can use awk.

Sort on multiple dis-contiguous keys/fields (can even specify key number/field from the end)

Notes: 1) -n-1 means sort key is the last field 2) -l is important if each separate record is on a new line (usually so for text files) 3) -j tells msort not to create log file (msort.log) in the working directory 4) may need to install msort package. 5) msort does lot more. Check man msort

Multi-segment file downloading with lftp

This is for files only, for directories 'mirror' has to be used.

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials
