Space used by files listed by ls -lt

Use awk to sum and print the space used by a group of files. It works well as long as the space used is not bigger than 79094548.80... I found that upper limit when trying to find out what was the total amount of recoverable space from a set of directories: user@servername:/home/user/scripts>for dirName in aleph_bin aleph_sh aleph_work dailycheck INTERFAZ ; do echo "${dirName} = $(cat /tmp/purge_ocfs_dir.*.log | awk '{sum+=$5} END {printf "%4.2f", sum}') "; done aleph_bin = 79094548.80 aleph_sh = 79094548.80 aleph_work = 79094548.80 dailycheck = 79094548.80 INTERFAZ = 79094548.80 In the worst case scenario, the total number might be almost 137G. user@servername:/home/user/scripts>df -h /ocfs/* Filesystem Size Used Avail Use% Mounted on //argalephfsprod/aleph_bin$ 137G 38G 99G 28% /ocfs/aleph_bin //argalephfsprod/aleph_sh$ 137G 38G 99G 28% /ocfs/aleph_sh //argalephfsprod/aleph_work$ 280G 135G 146G 49% /ocfs/aleph_work //argalephfsprod/dailycheck$ 137G 38G 99G 28% /ocfs/dailycheck //argalephfsprod/INTERFAZ/ 137G 38G 99G 28% /ocfs/INTERFAZ Any suggestion about how to get the correct amount of space for total over 80 Mbytes?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Advanced python tracing

Trace python statement execution and syscalls invoked during that simultaneously

execute your commands and avoid history records

$ secret_command;export HISTCONTROL= This will make "secret_command" not appear in "history" list.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

peak amount of memory occupied by any process with "FOO" in its name

Show the maximum amount of memory that was needed by a process at any time. My use case: Having a long-running computation job on $BIG_COMPUTER and judging whether it will also run on $SMALL_COMPUTER. http://man7.org/linux/man-pages/man5/proc.5.html VmHWM: Peak resident set size ("high water mark")

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

Lists unambigously names of all xml elements used in files in current directory

This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.

Display all shell functions set in the current shell environment

Uses the shell builtin `declare` with the '-f' flag to output only functions to grep out only the function names. You can use it as an alias or function like so: alias shfunctions="builtin declare -f | command grep --color=never -E '^[a-zA-Z_]+\ '" shfunctions () { builtin declare -f | command grep --color=never -E '^[a-zA-Z_]+\ '; }

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Make backups recurse through directories

find and delete empty dirs, start in current working dir
